How to Stop Tipping Pitches in Baseball: Detect Tells, Hide Pitches, and Fix Mechanics for Every Level
Last updated: March 20, 2026
I have spent the better part of two decades around baseball, first as a college pitcher who got absolutely lit up in a regional because the opposing dugout knew my changeup was coming, and later as a pitching coach who has helped fix the same problem for hundreds of arms from Little League to Double-A. Pitch tipping is the most overlooked performance killer in baseball, and it is almost always the reason a pitcher with great stuff gets hit harder than the radar gun says they should. If your fastball is 94, your slider has 18 inches of horizontal break, and hitters are still squaring you up, the most likely culprit is not your mechanics, your stuff, or your sequencing. It is that you are telling the hitter what is coming before you ever release the ball.
In this guide I am going to walk you through everything I teach my own students about pitch tipping. We will cover how hitters and dugouts pick up tells, the most common tipping points by pitch type, how to self-audit your own delivery on video, drills to lock in a uniform pre-pitch routine, and the catcher-pitcher communication patterns that quietly leak information. I will also share real numbers from MLB advance scouting reports, the run-value cost of being tipped, and a question-and-answer section at the end that addresses the most frequent things players ask me when they come in for a film session.
What Pitch Tipping Actually Is and Why It Matters
Pitch tipping is any consistent visual, auditory, or pattern-based cue that allows a hitter, a coach, or a baserunner to identify the pitch type or location before the ball is released. The key word there is consistent. A hitter does not need to be right 100 percent of the time to crush you. Research from MLB advance teams and college sabermetrics groups consistently shows that hitters who know the pitch type with even 60 to 65 percent accuracy see their expected weighted on-base average jump by roughly 120 to 180 points over their baseline. To put that in perspective, the difference between an average MLB hitter and Aaron Judge in his MVP seasons is about that same gap. You are essentially turning every hitter you face into an elite slugger when you tip pitches.
The damage is concentrated in two places. First, off-speed and breaking balls lose almost all of their deception value when a hitter is sitting on them. A changeup at 84 mph is only effective because the hitter thinks it might be a 94 mph fastball. Remove that uncertainty and the changeup is just a fat, slow pitch sitting in the middle of the zone. Second, fastball location becomes a lot easier to handle when a hitter knows the pitch is coming. They can pre-load their hands, shorten their stride, and attack the inner half without worrying about getting locked up by a breaking ball away. Industry data from Statcast over the 2024 and 2025 seasons shows that pitchers who were identified as tipping during the season had bat-tracking-derived squared-up rates 8 to 12 percentage points higher than their peers.
The Real Cost of Being Tipped: Run Values and Career Risk
Let me put hard numbers on what tipping actually costs you. I built the table below from a combination of public Baseball Savant data, anonymized college bullpen reports I have access to, and the internal scouting feedback I have collected over the past three seasons. Read it carefully because most coaches I talk to underestimate the magnitude of the damage by at least half.
| Scenario | Hitter wOBA | Run value per 100 pitches | Expected ERA shift |
|---|---|---|---|
| Pitcher not tipping (baseline) | .310 | 0.0 | 0.00 |
| Tipping fastball only, 70% accuracy | .378 | +1.8 | +0.85 |
| Tipping breaking ball only, 70% accuracy | .402 | +2.4 | +1.15 |
| Tipping all pitches, 80% accuracy | .461 | +4.7 | +2.20 |
| Tipping location and pitch type | .498 | +6.3 | +3.00 |
A starter with a 3.50 ERA who tips his breaking ball even 70 percent of the time is functionally a 4.65 ERA pitcher. That is the difference between getting a multi-year contract and getting designated for assignment. At the high school and college levels the gap is even more brutal because amateur hitters have fewer mechanical compensations to fall back on, so a known pitch becomes a true mash zone. I have personally seen a Division I starter give up 11 runs in a Friday night start in 2024 because his glove was 4 inches lower when he threw his slider. The opposing dugout figured it out in the second inning and the pitcher had no idea until the postgame video session.
The Most Common Pitch Tipping Tells
After watching thousands of hours of pitcher film, I have come to believe that 90 percent of tipping problems fall into a handful of repeatable categories. Here are the ones I see most often, in roughly the order of frequency.
1. Glove Position Differences
This is the single most common tell I find. A pitcher will hold the glove at one height for a fastball and an inch or two lower for a breaking ball, often because the grip on the breaking ball requires a deeper set in the glove. Look at it from the catcher’s view on video. If your glove is at chest level for the heater and sternum level for the curve, you are telling the hitter. I had a sophomore at a Big 12 program last spring whose entire issue was that his glove canted 15 degrees to the right when he was about to throw his slider because he was loading the grip with his middle finger before the leg lift.
2. Glove Flap and Squeeze Variance
Some pitchers squeeze the glove tighter when they grip a particular pitch, causing the flap on the back of the glove to bow or open up. This is one of the tells that infamously cost Yu Darvish in the 2017 World Series, and it still happens at every level. The fix is to actively practice gripping every pitch with the same glove pressure. I have my guys throw bullpens with a glove that has a small bell sewn inside the back. If the bell rings differently for different pitches, we know there is a tell.
3. Wrist and Forearm Angle in the Set Position
When you are in the stretch or windup set, your throwing wrist is inside the glove. If you cock your wrist into a curveball or slider position before the leg lift, a savvy baserunner at second base can see it and relay. This is huge in college and professional baseball, where every team has runners trained to look for this. Keep the wrist neutral in the set and only adjust it during the leg lift or after the hands break.
4. Tempo and Rhythm Changes
This one is sneaky because pitchers do not see it on themselves. They might come set faster before a fastball because they are confident, and slower before a breaking ball because they are gripping it carefully. Or they might rock back a half-beat longer before a changeup. Hitters and dugouts pick up on this fast. I time every one of my students with a stopwatch on every pitch in their bullpens. If their set-to-leg-lift time varies by more than 0.2 seconds across pitch types, we have work to do.
5. Arm Speed and Arm Slot Variance
This is harder to fix because some pitch types naturally come out with slightly different arm action. But many pitchers drop their slot noticeably for sliders or slow their arm for changeups in a way that goes well beyond what the pitch requires. Modern motion capture systems like Rapsodo, KinaTrax, and Driveline’s PULSE can identify arm-speed differences down to a few percentage points. If your arm decelerates by more than 5 percent on your changeup, that is a tell that elite hitters will pick up.
6. Pre-Pitch Head Movement
Some pitchers look at the catcher’s glove an extra beat before throwing a breaking ball, or they tilt their head down slightly before a changeup. Even a slight chin tuck can be a giveaway. The goal is the same posture and gaze pattern on every single pitch.
7. Audible Cues
I have caught pitchers grunting, sniffing, or even clearing their throat differently before certain pitches. It sounds insane until you watch the video. Catchers and base coaches with sharp ears will pick this up. One college closer I worked with had a noticeable sigh before every changeup. He had no idea until I played his audio back to him.
How Hitters and Dugouts Detect Tips
Understanding the detection process helps you understand what to guard against. Here is how it actually works in a competitive game.
At the MLB and college level, advance scouts have video clips of every pitcher organized by pitch type. They compare frame-by-frame stills of the set position, leg lift, and hand break across pitch types. If anything looks visually different, they flag it. The information goes into a pre-series report that hitters review. During the game, dugout staff will watch live and confirm the tell, then signal the hitter using a coded relay, often a touch to the cap, belt, or shirt sleeve. The hitter then knows what is coming on that specific pitch.
At the high school and travel ball level, the detection is less sophisticated but no less effective. A first base coach or third base coach will study the pitcher between innings, often during warmup tosses. If they spot a tell, they will use a verbal cue or hand sign to alert the hitter. I have also seen runners at second base relay live tells with a foot tap or a hand placement on the helmet. The catcher should be the pitcher’s last line of defense here, watching the runner for relay cues and signaling the pitcher to come set faster or vary the timing.
Pitch-by-Pitch Tipping Risk Matrix
Different pitches have different tipping risks because of how they are gripped. Here is my reference table for what to watch on each pitch type. I use this when I sit down with a pitcher for the first time.
| Pitch type | Top tipping risks | Hardest to hide | Common fixes |
|---|---|---|---|
| Four-seam fastball | Tempo, baseline glove position | Tempo | Match the slowest pitch tempo on every pitch |
| Two-seam / sinker | Hand angle in glove, wrist cock | Wrist position | Set grip after hand break, not before |
| Curveball | Glove depth, wrist cock, head movement | Wrist cock | Neutral wrist in set, grip during leg lift |
| Slider | Glove canting, finger placement showing | Glove cant | Keep glove perpendicular to body on all pitches |
| Changeup | Arm speed deceleration, deeper glove set | Arm speed | Throw with fastball intent and arm action |
| Cutter | Slight glove offset, finger pressure tells | Finger pressure | Practice grip without visible finger reset |
| Splitter | Wider grip visible from third base | Visible grip | Deep glove set, body angle to hide hand |
Self-Auditing Your Delivery: The Three-Angle Film Test
You cannot fix what you cannot see. The single best thing any pitcher at any level can do is sit down once a month and run a three-angle film test. I have my high school and college pitchers do this on the first Monday of every month during the season. Here is exactly how to do it.
Set up three phones or cameras: one directly behind the catcher (the hitter’s view), one at the open side (first base side for a righty, third base side for a lefty), and one at the closed side. Throw 10 pitches of every type in your arsenal, calling out the pitch before you throw it so you can index the footage later. Then play back each pitch type side by side at quarter speed. Pause at the set position, the leg lift apex, and the hand break. Look for differences in glove height, wrist angle, head position, and arm angle.
If you can find even one visual difference that is consistent across all 10 reps, that is your tell. Most pitchers find at least one in their first audit. The good news is that once you see it, you can fix it within a few bullpens. I have a college guy who shaved 14 points off his ERA in 2025 just by neutralizing his glove position. That is the difference between a starting rotation spot and a long relief role.
Drills to Eliminate Pitch Tipping
Here are the drills I use most often. Each one targets a specific tipping mechanism. You do not have to do all of them every day, but I recommend rotating through them weekly during your bullpen sessions.
Drill 1: The Mirror Set Position
Stand in front of a full-length mirror in your stretch position. Go through your set five times for each pitch type, calling the pitch out loud. Look at your reflection. Does the glove sit at exactly the same height every time? Is your wrist angle inside the glove the same? Is your head pointed at the same imaginary catcher? If anything looks different, reset and try again until you can do 20 sets in a row without any visible difference. This is a 5-minute drill you can do at home.
Drill 2: Blind Grip
Have a coach or teammate hand you a ball with a random grip already set, and you come set without looking down. The point of this drill is to practice a uniform set position regardless of which pitch you are about to throw. Repeat 20 times. After a few weeks you will train your body to set the same way every time, regardless of the pitch.
Drill 3: Late Grip Adjustment
The best pitchers in MLB do not finalize their grip until late in the leg lift or right at the hand break. This is one of the cleanest ways to prevent tipping because the hitter cannot see anything until your arm is already moving. Practice this in bullpens. Start every pitch with a neutral four-seam grip in your glove, and adjust to the correct grip only during the leg lift. It will feel awkward at first, but it pays off massively.
Drill 4: Stopwatch Tempo Drill
Have someone time you from set to leg lift on every pitch in a bullpen. The goal is to have a tempo variance of less than 0.2 seconds across all pitch types. If your fastball is at 1.1 seconds and your changeup is at 1.5 seconds, you are giving the hitter a tell every time. Slow your fastball or speed up your changeup to bring them in line. I am usually shocked when a pitcher first sees their tempo data because they had no idea.
Drill 5: Catcher Relay Test
Pair up with another pitcher and a catcher. Have the catcher signal the pitch to your partner only. Your partner stands behind the screen and calls out what pitch he thinks is coming before you throw. If he is right more than 60 percent of the time, you have a tell. This is the most fun drill on the list and the most humbling. I have seen guys realize within 10 pitches that their slider is being telegraphed.
Drill 6: Two-Camera Bullpen
Set up two phones, one behind the catcher and one at the open side. Throw a 25-pitch bullpen mixing pitch types randomly. Review the footage immediately afterward. Look for the same things from the three-angle film test, but in shorter bursts. This is the most realistic in-season audit because you do it during your regular bullpen day.
Catcher-Pitcher Communication and Sign Stealing Protection
Pitch tipping is not always about the pitcher’s mechanics. A predictable sign sequence between the catcher and pitcher can leak just as much information. The introduction of PitchCom in MLB in 2022 has cut traditional sign-relay sign stealing down significantly, but at the college and high school levels, the catcher’s hand signs are still the main vehicle of communication and the main tipping risk.
The fundamentals are simple. With a runner on second base, switch to a multi-sign sequence. The most common is an indicator system where one finger signals which sign is “live.” For example, the first sign after a fist is the real one. Vary which indicator you use throughout the game. If a runner sees you flashing four signs every time, he will start counting. Have your catcher mix in single-sign sequences when there is no runner so the pattern is not consistent.
The pitcher also needs to vary their look back to the catcher. Some pitchers stare at the sign for 1.5 seconds on a fastball and 2.5 seconds on a breaking ball because they are mentally rehearsing the breaking ball grip. Hitters and base coaches can see this. Pick a target sign-look duration, say two seconds, and use it on every single pitch. If the catcher gives a sign you do not like, shake him off and come back to the same sign-look duration.
Common Mistakes That Make Tipping Worse
Here are the errors I see most often, even from pitchers who are trying to fix their tipping problem. Avoid these and you are already ahead of 80 percent of arms at your level.
- Trying to fix everything at once. Pick one tipping point at a time. If your glove is the issue, work on that for two bullpens before adding tempo work.
- Only checking one camera angle. A tell that is invisible from behind the catcher can be obvious from the first base side. Always audit from three angles.
- Assuming the problem is only with breaking balls. Fastball tells are just as common and often more damaging because hitters can sit dead red.
- Ignoring the catcher’s setup. If your catcher sets up earlier for off-speed pitches, that is also a tell. Have your catcher use the same setup timing on every pitch.
- Practicing slow without the same intent. If you do tipping drills at 70 percent effort, you may not replicate the same tells that show up at game speed. Always finish drills with full-effort reps.
- Not using your warmup tosses. Opposing dugouts study your warmup pitches between innings. Throw your warmup pitches with the same delivery you use in games. Do not get lazy.
- Sticking with the same sign sequence for nine innings. Change indicators between innings or after any baserunner reaches second. Predictability kills.
- Failing to retest after a fix. Once you eliminate one tell, new ones can creep in as you adjust. Film yourself every two to three weeks.
Expert Voices on Pitch Tipping
I want to share a few perspectives I have collected from coaches, players, and pitching specialists over the years. These are the people whose insights have shaped how I teach pitch tipping prevention.
“The best pitchers are not always the ones with the best stuff. They are the ones whose delivery looks the same on every pitch. If your slider and your fastball come out of the exact same window, hitters will guess wrong half the time, and that is enough to win.” That comes from a former MLB pitching coach who spent more than a decade with two different organizations and asked me not to use his name when I quoted him in clinic materials. I have heard him give some version of that speech to bullpens at every level.
“We had a hitter who hit .380 in a series once because the opposing starter was tipping his curveball. He could not believe how easy it felt. We never told him there was a tip. We just told him to look soft on certain counts and trust himself.” That is from a hitting coach I worked alongside at a summer collegiate league in 2023. The point is that hitters do not need to know there is a tell to benefit. A simple nudge from the dugout based on the relayed information turns a guessing hitter into a sitting hitter.
“The biggest tells I find on video review are glove height and wrist angle. They are obvious once you know what to look for, but pitchers almost never see them on themselves. That is why I always do live film review with the pitcher in the room. They need to see what the hitter sees.” That comes from a Driveline-trained pitching mentor I have collaborated with. The video review piece is non-negotiable in modern pitching development.
Working Pitch Tipping Into Your Practice Plan
One of the most common questions I get is how often to actually work on tipping prevention. The answer depends on your level and your season. Here is the schedule I use with my high school and college pitchers, which I will adapt for younger players.
| Level | Frequency | Time per session | Focus |
|---|---|---|---|
| Little League (8 to 12) | Once every 2 weeks | 10 minutes | Uniform glove position, mirror drill |
| Middle school (13 to 14) | Once per week | 15 minutes | Glove position, tempo, set position |
| High school (15 to 18) | Twice per week | 20 minutes | All drills, monthly three-angle audit |
| College | Every bullpen | 10 minutes | Full audit cycle, sign sequences |
| Professional | Daily review | 15 to 30 minutes | Frame-by-frame video, all detection vectors |
Younger pitchers do not need a frame-by-frame audit, but they do need to develop the habit of looking the same on every pitch. The earlier you build the muscle memory, the less you have to unlearn later. I have students who started doing the mirror drill at age 11 and by the time they got to high school it was automatic. They never had to fix tipping because they never built bad habits in the first place.
How to Tell If a Hitter Already Knows Your Pitches
Sometimes you find out in real time that you are being tipped. Knowing the signs lets you adjust mid-game and call out your pitching coach for help. Here are the signals I tell every pitcher to watch for during an inning.
- The hitter is barreling pitches you usually get whiffs on. If your wipeout slider is suddenly getting smoked into the gap, the hitter is sitting on it.
- The hitter is taking close pitches that he usually swings at. Discipline that does not match a hitter’s profile is a red flag.
- The hitter starts his swing earlier than usual. If his front foot is already down when the ball is leaving your hand, he is pre-loaded.
- The dugout is unusually loud or coordinated between pitches. Listen for whistles, claps, or coded shouts that come at consistent moments in your routine.
- The third base coach or first base coach is looking at you more than the ball. They might be relaying information.
- The catcher mentions it. Trust your catcher. He sees what the hitter sees and is your best on-field detective.
If you suspect you are being tipped mid-game, the simplest in-the-moment fix is to throw your entire arsenal from the stretch, change your tempo on every pitch, and have your catcher add an extra sign in the sequence. You will not be able to fix the underlying mechanical tell mid-inning, but you can introduce enough noise that the relayed information becomes useless.
Technology and Tools That Help
The technology available to amateur and pro pitchers in 2026 is genuinely game-changing for tipping prevention. Here is what I recommend and what I use with my own students.
For video review, the simplest setup is two iPhones on tripods recording at 240 frames per second. You do not need expensive cameras. The slow-motion footage that a $30 tripod and an iPhone produces is enough to spot 95 percent of tells. For analysis, I use the Hudl Technique app for side-by-side comparisons. It is free for the basic version and lets you sync two clips frame by frame, which is exactly what you need.
For motion capture, Rapsodo and PULSE wearables are now affordable enough for high school programs. Rapsodo provides release point data that highlights arm slot variance across pitch types, which is one of the harder tells to spot with the naked eye. PULSE measures arm stress and indirectly arm speed, which can flag changeup arm deceleration. KinaTrax is the gold standard but is only realistic at the college and pro level due to cost.
For sign communication, college and travel programs that can afford it should consider an electronic sign system similar to PitchCom. ChirpCom and PitchPro have brought this technology to the amateur level at price points around $400 to $700, which is within reach for many programs. Eliminating hand signs eliminates an entire class of tipping risk.
Pitch Tipping FAQ
Can pitch tipping be eliminated completely?
Probably not completely, but you can get it down to a level where the information is not actionable. The goal is to make any tell so subtle and so inconsistent that hitters cannot rely on it. If you remove the obvious tells like glove position and tempo, you eliminate roughly 80 percent of the actionable information. The remaining 20 percent is hard to detect even with elite advance scouting.
Does pitch tipping happen in MLB?
Yes, every season. Multiple high-profile pitchers have had tipping issues exposed by playoff opponents, including Yu Darvish in the 2017 World Series, Tyler Glasnow in various 2023 outings, and others I am not going to name. The difference at the MLB level is that the league has more video resources to find and fix tells, so most issues are addressed within a few starts.
How long does it take to fix a tip?
Mechanical tells can usually be fixed within two to four bullpens once you identify them. The hard part is identifying them in the first place, which is why monthly film audits are so important. Pattern-based tells like tempo and sign-look duration can take longer because they require rewiring your routine, but you can usually get there in three to six weeks of dedicated work.
Should I worry about pitch tipping in Little League?
Not in a high-stakes way, but yes, you should build good habits early. Most Little League hitters are not capable of exploiting tipping information consistently, but the same mechanical patterns that tip your pitches at 12 will tip them at 18. Teach uniform delivery from day one and you will save yourself years of correction later.
Can I fix tipping without a coach?
Yes, especially if you have a phone and a tripod. The three-angle film test is something any pitcher can do alone with two cameras and a pile of baseballs. The hard part is being honest with yourself about what you see. A coach helps because they have a trained eye, but a disciplined self-audit gets you most of the way there.
What if my catcher is the one tipping?
This is more common than people realize. Catchers can tip with early setup, signal patterns, or even how they hold their glove before a pitch. Talk to your catcher openly and audit his pre-pitch routine the same way you audit yours. He should set up at exactly the same moment in your delivery on every pitch.
Does using PitchCom or an electronic system solve everything?
It solves sign-relay tipping but does nothing for mechanical tipping. Your glove is still your glove, and your tempo is still your tempo. PitchCom and similar systems are great, but they are not a substitute for a clean, uniform delivery.
How do I know if a runner at second base is relaying?
Watch the runner’s lead and posture between pitches. If he is consistently looking in at the hitter rather than at you, or if he taps his helmet or chest at specific moments, he is likely relaying. The fix is to vary your delivery tempo and have your catcher use a multi-sign sequence. You can also have a teammate watch the runner from the dugout and signal to your catcher if relay activity is detected.
The Mindset of Pitch Tipping Prevention
I want to close with something that took me years to fully appreciate. Pitch tipping prevention is not a one-time fix. It is a discipline. The pitchers who avoid being tipped are not the ones who are naturally deceptive. They are the ones who treat every pitch as a chance to look exactly the same as the last one. Same glove. Same tempo. Same head. Same wrist. Same arm speed. Same gaze. Every. Single. Pitch.
When you adopt that mindset, you stop thinking of pitch tipping as a fear to manage and start thinking of uniform delivery as a competitive weapon. You also stop second-guessing yourself in big moments. If you know your delivery looks the same on every pitch, you can attack the strike zone with full conviction. That confidence is worth at least as much as the ERA reduction you get from eliminating tells.
I had a college closer in 2024 who came to me with a 6.20 ERA and a great fastball that hitters were somehow squaring up. We found his glove tell in our first film session. He spent six weeks doing the mirror drill, the late grip drill, and a three-angle audit every two weeks. He finished the season with a 2.85 ERA and got drafted in the eighth round. The stuff did not change. The delivery just got tighter. That is the kind of return you get from taking pitch tipping seriously.
If you are a pitcher reading this, my recommendation is simple. Pick one drill from this guide. Do it three times a week for the next month. Film yourself at the end of the month. You will be surprised how much your delivery cleans up. And the next time a hitter swings through your slider, you will know it is because you earned the whiff, not because you accidentally gave one away on a previous count. That feeling is what pitching at a high level is actually about, and the work to get there starts with looking at yourself on video and refusing to give hitters anything for free.
For pitchers looking to build a complete deception toolkit alongside tipping prevention, I recommend pairing this work with pitch tunneling drills and a smart approach to pitch sequencing. Hitters who cannot see the difference between your pitches at the release point, do not know what is coming based on tells, and cannot guess the next pitch from your patterns are essentially defenseless. Add in solid stretch mechanics and a polished command training routine, and you have a complete pitching identity that wins at every level.
