How to Score a Baseball Game: Scorebook Symbols, Notation, and Step-by-Step Guide
Last updated: March 22, 2026
I learned to score a baseball game sitting next to my grandfather in the third-base bleachers of a minor league park when I was eight years old. He kept a battered Bob Carpenter scorebook on his lap, a stubby golf pencil in his right hand, and a cold hot dog in his left. By the end of nine innings, that scorebook told a better story than any broadcaster could. Every pitch, every runner, every defensive shift, every questionable umpire call – all of it was there in lines, numbers, and symbols that looked like hieroglyphics to me at the time. Twenty-five years later, I still score most of the games I attend, and I have taught hundreds of players, parents, and coaches to do the same.
If you have ever picked up a scorebook and felt intimidated by the grid of diamonds, the numbered positions, and the shorthand, this guide is for you. By the end of it, you will understand the notation system, you will be able to score every type of play you can encounter in a baseball game, and you will know the tricks that professional scorekeepers use to keep up with a fast-paced big league broadcast. I have scored Little League, high school, college summer ball, independent ball, and spring training games, and I am going to walk you through the entire system the way I wish someone had walked me through it.
Why Scoring a Baseball Game Still Matters in 2026
With Statcast data streaming to our phones and MLB Gameday showing every pitch in real time, it is fair to ask whether scoring a game by hand is still worth the trouble. I hear this question from parents at every clinic I run, and my answer is always the same: scoring a game is not about recording data, it is about watching the game. When you score, you are forced to pay attention to every pitch, every defensive alignment, every tag-up, every passed ball. You notice things you would otherwise miss. You build a mental library of situations that makes you a smarter player, coach, or fan.
For youth coaches, the scorebook is also the official record of the game. If a protest is filed, if a pitcher hits a pitch-count limit, if a tournament director wants to verify an eligibility rule, the book is the first thing they ask to see. Little League Baseball’s 2026 rulebook still requires pitch counts to be recorded by both teams, and the scorebook is the accepted format. High school and college coaches use the book to track on-base percentage, batting average with runners in scoring position, and pitcher efficiency in ways that a simple box score cannot capture.
Equipment You Need to Score a Game
You do not need much to start scoring, but using the right tools makes the job dramatically easier. I have scored games on everything from a napkin to a custom-bound leather scorebook, and after a lot of trial and error, this is the kit I bring to every game.
| Item | Why You Need It | My Recommendation |
|---|---|---|
| Scorebook | Pre-printed grids with innings, batter slots, and pitch boxes | Bob Carpenter Project Scorebook (pro style) or C.S. Peterson’s Scoremaster (classic youth style) |
| Mechanical pencil | Clean lines, no sharpening, erases cleanly for corrections | Pentel 0.7mm with HB lead |
| Good eraser | You will make mistakes, especially on complex plays | Pentel Hi-Polymer white eraser |
| Two or three colored pens | Differentiate runs, errors, and pitching changes | Pilot G-2 in red and blue, plus black |
| Clipboard or hard surface | Stability for writing in bleacher seats | Masonite clipboard, 9×12 inch |
| Lineup cards | Record starting lineups and substitutions cleanly | Print a simple template or buy laminated cards |
| Pitch counter (optional) | Backup for verifying pitch counts | GoGo Sports four-unit clicker |
| Radar gun app (optional) | Record velocity if the venue does not post it | Pocket Radar or free phone-based estimators |
If you are just starting out, I would recommend the C.S. Peterson’s Scoremaster. It is the scorebook most youth leagues in the United States hand out to team parents, and the layout is forgiving. Once you are comfortable with the basics, graduate to the Bob Carpenter Project book, which gives you dedicated pitch-tracking boxes and more room for notation.
The Language of Scoring: Position Numbers and Symbols
Before you can score a single out, you have to learn the vocabulary. Baseball scoring uses numbers one through nine to represent the nine defensive positions on the field. These numbers are fixed, they never change, and memorizing them is the single most important step in learning to score. If someone wakes you up at three in the morning and asks what the second baseman is, you should be able to say “four” without thinking.
| Number | Position | Abbreviation |
|---|---|---|
| 1 | Pitcher | P |
| 2 | Catcher | C |
| 3 | First Baseman | 1B |
| 4 | Second Baseman | 2B |
| 5 | Third Baseman | 3B |
| 6 | Shortstop | SS |
| 7 | Left Fielder | LF |
| 8 | Center Fielder | CF |
| 9 | Right Fielder | RF |
| DH | Designated Hitter | DH |
The thing that trips new scorers up is that first base is three and shortstop is six, not the other way around. The trick I teach is to trace the infield counterclockwise from the pitcher’s mound: one is the pitcher, two is the catcher, three is first, four is second, five is third, and six is shortstop. Then the outfield goes left to right: seven, eight, nine.
Common Scoring Abbreviations Every Scorer Must Know
Position numbers are the nouns of scoring. Abbreviations are the verbs. Once you know what each abbreviation means, you can write down any play in a handful of characters.
| Abbreviation | Meaning | Example |
|---|---|---|
| K | Strikeout swinging | Big K in the batter’s diamond |
| Backwards K | Strikeout looking (called third strike) | Mirror-image K |
| 1B | Single | Line drive to right field = 1B-9 |
| 2B | Double | Gap shot to left-center = 2B-78 |
| 3B | Triple | Ball off the wall in right = 3B-9 |
| HR | Home run | Over the fence in left = HR-7 |
| BB | Base on balls (walk) | BB in the box |
| IBB | Intentional walk | IBB or dotted line |
| HBP | Hit by pitch | HBP in the box |
| SAC | Sacrifice bunt | SAC with the fielding sequence |
| SF | Sacrifice fly | SF-8 for a fly to center that scores a run |
| FC | Fielder’s choice | FC-6-4 on a grounder that forces the lead runner |
| E | Error | E6 for a shortstop error |
| WP | Wild pitch | WP in the margin |
| PB | Passed ball | PB in the margin |
| SB | Stolen base | SB2 for steal of second |
| CS | Caught stealing | CS2-2-4 on a caught steal of second |
| BK | Balk | BK in the margin |
| DP | Double play | DP-6-4-3 |
| TP | Triple play | TP with the fielding sequence |
Step-by-Step: Scoring a Game from the First Pitch
Now that you have the vocabulary, here is the exact sequence I follow from the moment I sit down at the ballpark. If you work through these steps in order for your first three or four games, the rest will become muscle memory.
Step 1: Fill Out the Lineup Cards
About fifteen minutes before first pitch, both managers exchange lineup cards with the umpire. Get the home and away lineups, then write each player’s name, uniform number, and defensive position in the correct slot of your scorebook. In a nine-player lineup without a designated hitter, each player gets a row. In a ten-player lineup with a DH, the DH takes the slot of the player he is hitting for. Write the pitcher’s name in the row where he actually bats, or in the DH slot if the game uses the DH rule.
Step 2: Record the Starting Pitchers
In the pitcher tracking section of your book (usually a strip at the bottom or a separate page), write down the starting pitcher for each team, the time of first pitch, and leave space to record the pitching line. Most scorebooks have columns for innings pitched, hits, runs, earned runs, walks, and strikeouts. I also like to track pitch count by inning so I can see when a starter is fading.
Step 3: Score Each At-Bat in the Correct Cell
The body of a scorebook is a grid. Rows are batters in order. Columns are innings. Each cell contains a small diamond to track baserunning. The at-bat result goes in the middle of the diamond, and any advancement gets drawn along the base paths. For example, a single to left field by the leadoff hitter in the top of the first is written as 1B-7 in the middle of the diamond, with a line from home plate to first base. If he steals second on the next pitch, you draw a line from first to second and write SB2 next to it. If he is stranded at second when the inning ends, you close off the diamond and move on.
Step 4: Track the Out Number
Every time a batter makes an out, circle the out number (1, 2, or 3) in the bottom-right corner of his cell. This tells you at a glance how many outs there were when he came up, and more importantly, how many there were when a run scored. Knowing that a run scored with two outs on an error changes how the rest of the inning is scored.
Step 5: Draw the Run
When a runner scores, fill in the diamond completely (I use a dark shade) and write the RBI credit at the corner. If the run is unearned because of an error earlier in the inning, put a small E next to it so you remember when you tally earned runs for the pitcher at the end of the inning.
Step 6: Close Out the Inning
At the end of each half-inning, tally runs, hits, errors, and left on base in the column summary. Double-check that your three outs are circled correctly, that the runs you show match the scoreboard, and that you did not leave a runner drawn on base who actually scored.
Step 7: Record Substitutions Immediately
The moment a pitching change or a pinch hitter happens, draw a horizontal line under the last player’s row in the batting order, write the new player’s name and number below it, and note the inning in which he entered. If you wait, you will lose track, and five innings later you will have no idea who was playing second base in the sixth.
Step 8: Totals at the End of the Game
After the final out, tally each batter’s line (at-bats, runs, hits, RBIs), the pitchers’ lines, and the team totals. Confirm the final score matches the scoreboard. If a scoring decision (a questionable hit versus error) is in doubt, note it as TBD so you can research it later. Write the total time of the game, the attendance if posted, and any notes about the weather, injuries, or ejections.
Scoring Specific Plays: The Trickiest Situations
Most at-bats are simple. A groundout to short is 6-3. A fly out to center is F8. A strikeout swinging is K. But baseball is a game of edge cases, and these are the plays that separate beginner scorers from experienced ones.
The 6-4-3 Double Play
A ground ball to the shortstop, flipped to the second baseman for the force, who throws to first to double up the batter. In the runner’s cell (the previous batter still on first), write 6-4 and circle the out number. In the batter’s cell, write 6-4-3 DP and circle his out number. Some scorers also add a horizontal bracket connecting the two cells to show they were part of the same play.
The Sacrifice Fly
Runner on third, less than two outs, batter lifts a fly ball deep enough for the runner to tag up and score. In the batter’s cell, write SF-8 (or whichever outfielder). Circle the out number. In the runner’s previous cell, draw the line from third to home to show the scored run, and write SF next to it to note how he came around.
The Fielder’s Choice
Runner on first, batter hits a grounder to short. The shortstop throws to second to force the lead runner. The batter reaches first safely. This is not a hit and not an error – it is a fielder’s choice. In the batter’s cell, write FC-6-4. In the original baserunner’s cell, write 6-4 and circle his out number. The batter is now on first base and is credited with an at-bat but not a hit, which is why a fielder’s choice hurts your batting average.
The Dropped Third Strike
With first base unoccupied (or with two outs regardless), the batter may run to first if the catcher fails to catch strike three cleanly. If the batter reaches safely, write K-2 and put a small dot or notation to indicate he reached on the dropped third strike. The pitcher still gets credit for the strikeout, but the batter is not out. This is one of the most common scoring mistakes I see in amateur books.
The Catcher’s Interference
If the catcher’s mitt contacts the bat during the swing, the batter is awarded first base and it is charged as a fielding error against the catcher. Write CI-2 in the cell, and note that the at-bat does not count against the batter’s average.
The Balk
On a balk, every runner advances one base. Mark BK in the margin of the inning and advance each runner with a dashed line. The batter remains at bat with the same count.
The Overthrow
A ground ball to the first baseman who throws wildly over the head of the pitcher covering. Batter reaches on an error and advances an extra base. Write E3 in the batter’s cell and extend the baseline to second base. The pitcher does not get credit for the out, and any subsequent runs scored in that inning may be unearned if he would have been out with an errorless play.
Tracking Pitch Counts and Ball-Strike Counts
Modern scorebooks include a small box for each at-bat where you can track every pitch. The standard notation uses dots for balls and slashes for strikes, with additional symbols for pitch outcomes. I track pitch counts religiously because it tells me so much more about the pitcher’s performance than the final line score ever could.
| Pitch Outcome | Symbol | Notes |
|---|---|---|
| Called strike | . with a circle or C | Batter takes strike |
| Swinging strike | S or / | Whiff |
| Foul ball | F | Count caps at two strikes on fouls |
| Foul tip caught | FT | Counts as a strikeout if strike three |
| Ball | B or – | Pitch outside zone |
| In play | X or IP | Pitch put in play, follow up with result |
| Hit by pitch | HBP | Batter awarded first |
Little League Baseball’s 2026 pitch count rules require that a pitcher ages 11-12 cannot exceed 85 pitches in a day, and mandatory rest days kick in at 21, 36, 51, and 66 pitches. If you are keeping the book for a Little League team, the pitch count is an official number that can end a pitcher’s outing mid-batter. Double-check your count with the other team’s scorer between innings.
Common Mistakes New Scorers Make
I have corrected more scorebooks than I can count, and the same errors come up again and again. Learn to avoid these, and you will already be ahead of most amateur scorers.
| Mistake | Why It Happens | How to Fix It |
|---|---|---|
| Confusing first baseman (3) and third baseman (5) | Left-to-right thinking from the stands | Memorize the counterclockwise order: 1-2-3-4-5-6 |
| Failing to circle the out number | Distraction between pitches | Train yourself to circle out number before anything else |
| Missing the dropped third strike | Looks like a normal strikeout | Always note K-2 and whether batter reached |
| Crediting a hit on a fielder’s choice | Batter reaches base, feels like a hit | If a runner is forced out on the play, it is FC, not 1B |
| Forgetting pitching changes | Happens between innings | Draw the line the moment a new pitcher takes the mound |
| Not tracking the ball-strike count | Feels like extra work | Use dots and slashes; it takes two seconds per pitch |
| Scoring errors as hits | Batter looks safe, ball gets by fielder | Ask yourself: with ordinary effort, would the play have been made? |
| Missing RBIs | Forgetting to mark them immediately | Mark RBI in the corner of the cell as soon as the run scores |
| Leaving diamonds unclosed | Running out of time before the next pitch | Close the diamond at the end of each half-inning sweep |
| Mixing up the batter’s slot after a sub | Pinch hitters and double switches | Draw a clear horizontal line and start a fresh row for the sub |
| Writing too small or too large | Early books have limited cell space | Develop a consistent micro-handwriting style |
| Mixing pen and pencil | Looks messy, hard to erase | Pick one tool and stick with it for the full game |
Drills and Exercises to Improve Your Scoring
Scoring a game is a skill, and like any skill, it gets better with focused practice. These are the exercises I give to parents, team managers, and broadcasters who want to get fluent faster.
Drill 1: The MLB Network Replay
Pick an archived nine-inning MLB game on MLB.TV or YouTube. Pause after each pitch or at-bat and record the result before watching the next one. Because you can rewind, you can correct yourself in real time. Do this for three full games and you will be noticeably faster by the end.
Drill 2: The Silent Radio Game
Listen to a full game on the radio with the TV off. Radio broadcasters describe every play in detail, which forces you to build a mental picture and convert it to notation. This is harder than TV and develops listening skills that help when you score live at a ballpark.
Drill 3: The Youth Game Shadow
Go to a Little League or high school game where the official scorer is an experienced parent. Score the game alongside them, and compare notes inning by inning. They will catch things you miss, and they will show you shortcuts you did not know.
Drill 4: The Box Score Reverse Engineering
Grab a printed box score from the newspaper or a web archive and work backward to reconstruct possible scorebook entries. This teaches you how final totals flow from individual plays and forces you to think about what combinations of at-bats produce a given line.
Drill 5: The Speed Round
Set a timer for fifteen seconds and describe a play out loud: “Line drive to left-center, runner from first scores, batter thrown out trying to stretch it to a double.” Write the scoring notation before the timer goes off. Build up to complex double plays, passed balls, and overthrows. I use this drill with my fantasy league group before playoff season and it is remarkable how fast people get.
Advanced Scoring Techniques and Shortcuts
Once you can score a standard nine-inning game without panic, these tricks separate good scorers from great ones.
Color Coding
I use red ink for runs scored, blue ink for errors, and black pencil for everything else. When I glance at the book later, the story of the game pops out immediately. Two red diamonds in the fifth? I remember that was the inning the bullpen blew the lead. A cluster of blue in the eighth? The defense collapsed.
Spray Charts
Add a small field diagram to each batter’s cell and draw where the ball was hit. Over the course of a game, you build a visual record of a hitter’s tendencies. I share these with coaches before playoff matchups, and they are usually more useful than any analytics report.
Velocity Notation
If the scoreboard posts pitch velocity, I write the max velocity of each inning in the margin next to the pitcher’s line. You can see in real time when a starter’s fastball starts to drop two or three miles per hour, which is usually the signal that the manager should warm up a reliever.
Defensive Positioning Notes
With MLB’s shift restrictions in place since 2023, teams still cheat the infield and outfield for certain hitters. I note the defensive alignment in the margin (for example, “SS up the middle, 2B shaded to pull side”) when I see unusual positioning. This helps me understand why a ground ball found a hole or a fly ball landed where it did.
Umpire Tracking
Record the home plate umpire’s name and keep a tally of questionable calls. Over a season, you will notice that certain umpires have expanded zones, pitcher-friendly tendencies, or inconsistent outside corners. This is especially useful for high school and college tournaments where the same umpires work multiple games.
Game Situation Codes
In the top corner of each inning I write the situation code: H for home team batting, V for visitor, plus the running score. This prevents the embarrassing moment three hours later when you cannot remember what the score was going into the seventh.
Scoring for Different Levels of Baseball
The mechanics of scoring are the same at every level, but the pace and the situations differ in ways that affect how you manage the book.
Little League and Youth Ball
Expect lots of walks, wild pitches, passed balls, and errors. Pitch counts are critical because mandatory rest days are enforced. Batters may skip innings due to continuous batting order rules, so know whether the league uses a standard nine-player order or a continuous order. Scoring youth ball is slower in one sense (longer at-bats) but faster in another (more runners advancing on errors and wild pitches than you can keep up with).
High School
Games are typically seven innings with tiebreaker rules after that. High school has the designated hitter rule, and lineups can include up to ten players when a DH is used. Pay attention to the flex rule and re-entry rule for starters, which can get complex in late innings.
College
NCAA games are nine innings. The DH rule applies and substitution rules are more permissive than professional baseball. Metal bats mean more balls in play, more doubles in the gap, and quicker innings offensively. I write faster at college games than anywhere else.
Minor League and MLB
MLB and upper-minor league games since 2023 use a pitch clock (15 seconds with bases empty, 18 with runners in 2026 after the latest adjustment), a three-batter minimum for relievers, and restricted defensive shifts. The pitch clock in particular forces you to write quickly between pitches. The automatic runner at second base in extra innings (still in effect for regular season games in 2026) requires marking that runner and tracking him carefully, because runs he scores are unearned.
Digital Scoring: Apps and Hybrid Methods
Purists score by hand. I am mostly a purist, but I keep a few apps on my phone as backup. GameChanger is the dominant youth-baseball app in 2026 and it handles lineup management, pitch counts, and live streaming to parents automatically. iScore is a hobbyist favorite that gives you a full scorebook interface on a tablet. Bob Carpenter has his own companion app that mirrors the paper scorebook layout.
My recommendation: learn paper first. Apps will do the math for you and enforce rules automatically, which means you never have to think about them. That is fine if you just want a box score, but it is terrible if you want to understand the game. Score by hand for a full season, then add an app alongside it if you want the data portability. Not the other way around.
Official Scorer Rules: Hits vs Errors
One of the hardest judgment calls in scoring is distinguishing a base hit from an error. The standard from the MLB official scoring rules is this: if the fielder could have made the play with ordinary effort, and failed, it is an error. If the ball required extraordinary effort (a dive, a long run, a leap), and the fielder did not get it, it is a hit. The key words are ordinary effort.
I remind myself of a few tiebreakers. If the fielder touched the ball but did not glove it cleanly, that leans toward error. If the fielder misjudged the ball’s trajectory and it landed behind him, that can be either hit or error depending on how challenging the read was. If the fielder made the catch but then dropped the transfer, that is an error (assuming he had control long enough). Use consistency over the course of a game, document borderline calls in the margin, and when the official scorer at the stadium makes a ruling, note it and defer.
Calculating Earned Runs
At the end of each half-inning, you need to determine how many of the runs scored are earned. A run is unearned if an error earlier in the inning extended the inning or put a runner on base who later scored. The trick is to reconstruct the inning as if no errors had occurred. If the third out would have been recorded before the runs scored, those runs are unearned. If the run would have scored anyway, it is earned.
Example: two outs, runner on first via a single. Next batter hits a grounder to short that the shortstop boots (E6). Runners at first and second. Next batter singles, scoring the first runner. The run is unearned because without the error, the inning would have ended with the grounder to short.
When a relief pitcher enters mid-inning with runners on base, the earned runs for any of those runners who score are charged to the pitcher who put them on base, not the reliever. This is called an inherited runner, and most scorebooks have a separate column for it.
Frequently Asked Questions
What does a backwards K mean?
A backwards K indicates a strikeout looking, meaning the batter did not swing at strike three. A regular forward K is a strikeout swinging. Some scorers write both versions, others just use K for any strikeout and note whether the batter swung with a lowercase s or c.
How do you score a ground rule double?
Write GRD in the batter’s cell and advance any runners the required two bases. If a runner on first would have scored without the ball bouncing over the fence, he still only advances to third, because a ground rule double awards exactly two bases from the runner’s position at the time of the pitch.
Do you credit an RBI on a bases-loaded walk?
Yes. A bases-loaded walk forces in a run, and the batter gets credit for an RBI (even though he also gets a BB, not a hit). Mark RBI in the corner of his cell and advance the runner from third to home.
How do you score a caught stealing double play?
If the batter strikes out swinging and the catcher throws out the runner trying to steal, both outs are recorded in the same play. Write K in the batter’s cell with out number circled. In the runner’s cell, write CS2-2-6 (or whichever fielders made the tag), and circle his out number. Note the combined play as a strike-em-out, throw-em-out DP in the margin.
What if I miss a pitch or a play while I am writing?
It happens to every scorer. Leave a blank and confirm the play with someone nearby or check the scoreboard. If you cannot verify it, mark the cell with a question mark and write “TBD” so you know to check the official game log after the game. Better to have an honest gap than a fabricated entry.
Is it okay to use abbreviations my scorebook does not list?
Yes, as long as you are consistent. If you want to write “CHK” for a check swing, or “ROE” for reached on error, go for it. Just keep a small legend on the first page of your scorebook so you know what your own shorthand means six months later.
How long does it take to learn to score a game well?
Give yourself three games to learn the basics, ten games to get comfortable, and a full season to become fluent. The first game will feel overwhelming. By the fifth game, you will score at a reasonable pace. By the thirtieth game, you will be teaching someone else.
Do professional scorekeepers use the same notation I learn here?
Yes, mostly. MLB official scorers use the same basic symbols, position numbers, and terminology described in this guide. Individual scorers develop their own shorthand for edge cases, but the core language is universal. If you can score a high school game with this system, you can sit next to an MLB official scorer in the press box and follow along.
Can scoring from a livestream be as accurate as in person?
Almost. You lose the ability to see defensive positioning on pitches where the ball is not in play, and you miss the pre-pitch intelligence that comes from watching how fielders move. Otherwise, it is the same game. If anything, livestreams with replay make it easier to catch tricky plays because you can rewind.
What is the difference between a scorekeeper and an official scorer?
A scorekeeper keeps a scorebook for personal or team use. An official scorer is appointed by the league to make rulings on hits, errors, and other scoring decisions that are entered into the permanent statistical record. Official scorers at the MLB level are typically veteran journalists or former scorekeepers with decades of experience, and their rulings affect players’ stats and contract incentives.
Putting It All Together: My Final Advice
The first time I handed my scorebook back to my grandfather at the end of a game, I had missed a double play, credited two hits as errors, and lost track of the pitch count by the fourth inning. He grinned, told me to try again tomorrow, and handed me a fresh sheet. Scoring baseball is forgiving. The book is a record, not a test. The more games you score, the more the game reveals itself to you.
My best advice for anyone starting out is to commit to scoring a full season of your kid’s games, your college team, or a favorite MLB club. Score every single game. By the end of that season, you will understand baseball in a way that casual fans never will. You will notice the bunt signs, the shifts, the pitch sequencing, the way a pitcher’s velocity drops in the sixth, the way a manager’s bullpen decisions in April set up the tactics in October. The scorebook becomes a lens for seeing the game that no app or statistical dashboard can replace.
If you want to dive deeper into the strategic side of the game once your scorekeeping is solid, my guides on baseball batting order strategy, baseball signs and signals, and how to read baseball statistics will add layers to what you are already capturing in the book. The more you know about what the players and coaches are trying to do, the more meaningful every entry in your scorebook becomes.
Grab a scorebook, sharpen your pencil, and find a game this week. The first inning is always the hardest. The rest of the season is pure joy.
