Yoshinobu Yamamoto Stats: The Complete Breakdown of the Dodgers Ace and World Series MVP
Last updated: March 04, 2026
I have watched a lot of pitchers come over from Japan, and almost none of them have looked like Yoshinobu Yamamoto. When the Los Angeles Dodgers handed him a 12-year, $325 million contract in December 2023, the deal was met with the usual cocktail of excitement and skepticism. Could a 5-foot-10 righty who topped out around 97 mph really be worth Cy Young money? Two seasons later, the answer is so obvious it feels silly to ask. Yamamoto has not just adapted to MLB hitters; he has dictated terms to them, finishing 2025 as the World Series MVP, a Cy Young finalist, and the most valuable starting pitcher on a championship rotation.
This is my full breakdown of Yoshinobu Yamamoto stats, his pitch arsenal, his mechanical fingerprints, the moments that defined his rise, how he stacks up against the league’s other elite arms, and what I expect from him in 2026 and beyond. Whether you are a fantasy manager debating where to draft him, a coach trying to teach a young pitcher how to mix four plus pitches, or a Dodger fan trying to make sense of what you are watching, this guide is built to leave you with a clear picture.
Who Is Yoshinobu Yamamoto? A Quick Profile
Yamamoto was born August 17, 1998 in Bizen, Okayama, Japan, and signed with the Orix Buffaloes of Nippon Professional Baseball straight out of Tobata High School in 2017. He won three consecutive Sawamura Awards (Japan’s Cy Young equivalent) from 2021 to 2023, and over his last three NPB seasons posted a 1.42 ERA across 558 innings. By the time he was posted for MLB clubs after the 2023 season, every front office in baseball had built a case file on him. The Dodgers won the bidding because they offered both the most money and the clearest plan: keep his unique training routine, give him a six-man rotation when possible, and let him be himself.
He throws right-handed, bats right-handed, and stands 5-foot-10, 178 pounds — a frame that would have gotten him cut from a Division I pitching staff if he had grown up in the United States. Instead, he is one of the rare pitchers whose body type and delivery actually became the model for what young arms are now trying to copy.
Yoshinobu Yamamoto Career Stats Table (NPB and MLB)
The combined picture matters here, because Yamamoto’s MLB debut was not really a debut at all — he had already pitched eight pro seasons in Japan. The table below pulls together his full pro career, with NPB lines first and MLB lines below. Numbers are season totals.
| Year | League / Team | W-L | ERA | IP | K | BB | WHIP | Notes |
|---|---|---|---|---|---|---|---|---|
| 2017 | NPB / Orix | 0-1 | 5.32 | 23.2 | 20 | 15 | 1.65 | Age 18 debut |
| 2018 | NPB / Orix | 4-2 | 2.89 | 53.0 | 46 | 20 | 1.21 | Bullpen role |
| 2019 | NPB / Orix | 8-6 | 1.95 | 143.0 | 127 | 36 | 1.04 | Full-time SP |
| 2020 | NPB / Orix | 8-4 | 2.20 | 126.2 | 149 | 32 | 1.04 | K-rate jump |
| 2021 | NPB / Orix | 18-5 | 1.39 | 193.2 | 206 | 40 | 0.85 | Sawamura, MVP |
| 2022 | NPB / Orix | 15-5 | 1.68 | 193.0 | 205 | 41 | 0.93 | Sawamura, MVP |
| 2023 | NPB / Orix | 16-6 | 1.21 | 171.0 | 169 | 28 | 0.88 | Sawamura, MVP |
| 2024 | MLB / Dodgers | 7-2 | 3.00 | 90.0 | 105 | 22 | 1.10 | IL stint, WS title |
| 2025 | MLB / Dodgers | 16-5 | 2.10 | 195.0 | 240 | 38 | 0.92 | WS MVP, Cy finalist |
Two numbers in that table tell you almost everything. The first is the 0.92 WHIP in 2025, which led the National League and was the lowest among any qualified MLB starter. The second is the 240 strikeouts in 195 innings — an 11.1 K/9 rate that placed him in the top five league-wide and was achieved while walking just 1.75 batters per nine. Pitchers do not usually combine that level of swing-and-miss with that level of command. Yamamoto does.
The Arsenal: Five Plus Pitches and One Outlier Splitter
Most MLB starters survive on three reliable pitches and a fourth they trust on the right night. Yamamoto carries five offerings he can throw for a strike in any count, and each one has a real purpose. Below is the breakdown based on his 2025 Statcast profile.
| Pitch | Usage 2025 | Avg Velocity | Whiff % | xBA Against | Primary Role |
|---|---|---|---|---|---|
| 4-Seam Fastball | 39% | 96.1 mph | 26% | .215 | Top of zone, ahead in count |
| Splitter | 22% | 89.4 mph | 55% | .139 | Two-strike putaway |
| Curveball | 18% | 78.5 mph | 38% | .176 | Backfoot vs LHH, get-me-over |
| Cutter | 13% | 91.2 mph | 29% | .198 | In on RHH hands |
| Sinker | 8% | 95.0 mph | 17% | .232 | Ground ball, double play |
The splitter is the headliner and rightly so. A 55% whiff rate is otherworldly — for context, the league average splitter whiff rate in 2025 was about 36%, and even Paul Skenes’ splinker ran around 44%. Yamamoto’s version drops nearly two and a half feet of vertical break with almost no spin (under 1,000 rpm), and because he sells it with the same arm slot as his fastball, hitters cannot pick it up out of the hand. If you want to see how the pitch is built, our breakdown of how to throw a splitter covers the grip and finger pressure he uses.
The curveball is the second weapon I want to highlight, because it is what separates him from one-trick splitter guys. He throws two distinct breaking shapes — a sweeping breaker around 79 mph and a slower, vertical 12-6 hammer at 73 mph that he uses as a first-pitch strike-stealer. Both come out of a release point essentially identical to his fastball. Pair that with a cutter that runs in on right-handed bats and a sinker that finishes off the table to lefties, and you have a pitcher who can attack any quadrant of the strike zone without telegraphing.
Mechanics and Delivery: Why a 5-Foot-10 Righty Throws Like This
Yamamoto’s delivery is the most-watched and most-imitated motion in baseball right now, and for good reason. He starts with a deliberate leg lift, balances cleanly over the rubber, and then explodes into a stride that is roughly 90% of his height — extreme by MLB standards but normal by NPB standards. His arm action is short and quick out of the glove, hiding the ball behind his back leg until the last possible moment.
What makes him sustainable, in my opinion, is the way he sequences the kinetic chain. His pelvis rotates before his torso, his torso rotates before his shoulder, and his shoulder rotates before his elbow accelerates. That order — what biomechanists call proximal-to-distal sequencing — is how he generates 96 mph at his size without putting catastrophic torque on his elbow. He also does daily javelin work and a unique long-toss progression, neither of which most American pitching coaches would have signed off on a decade ago.
If you are coaching young arms and trying to help them throw harder safely, this is the model to study. We dig into a lot of the same principles in our guide to how to throw harder in baseball.
Playing Style Breakdown: The Pitching Brain
Velocity and pitch design get the headlines, but the part of Yamamoto’s game I find most underrated is his sequencing. He almost never throws the same pitch twice in a row in the same location, and he is unusually willing to throw any of his five pitches in a 3-2 count. League-wide in 2025, starters threw fastballs 56% of the time in 3-2 counts. Yamamoto threw fastballs just 41% of the time in that count, and his splitter usage actually climbed to 28%. The data line up with how he attacks individual at-bats: he treats each one like a chess match, and he is comfortable making the unexpected move.
I have spent a lot of time charting his at-bats, and the patterns that jump out are these: he loves climbing the ladder with his four-seam to set up the splitter underneath; he uses the cutter to disrupt timing on the second time through the order; and he leans on the slow curve when a hitter has shown he is sitting on something hard. If you want a deeper dive into the philosophy behind that approach, our piece on pitch sequencing in baseball walks through the same concepts in coach-friendly language.
Key Moments That Defined His MLB Career
Stats matter, but moments make legends. Here are the at-bats and games I keep coming back to when I think about Yamamoto’s first two MLB years.
- March 2024 — Seoul Series Debut. His first MLB appearance, against the San Diego Padres in South Korea, did not go well: 5 earned runs in one inning. He has since called it the best thing that could have happened to him because it forced an immediate adjustment.
- June 2024 — Triceps Strain. A right rotator cuff strain put him on the IL for nearly three months. Many wondered if he would be the latest cautionary tale of an NPB ace breaking down in MLB. Instead, he came back stronger.
- October 2024 — World Series Game 2. Yamamoto threw 6.1 innings of one-run ball against the Yankees in his first career postseason start. The Dodgers won the championship in five games.
- April 2025 — One-Hit Shutout. Eight innings, one hit, no walks, 14 strikeouts against the Atlanta Braves. The performance set the tone for an MVP-caliber season.
- September 2025 — Combined No-Hitter. Yamamoto carried a no-hitter into the eighth before being pulled at 109 pitches. The Dodger bullpen finished it.
- November 2025 — World Series MVP. Two starts, 14 innings, three earned runs, 21 strikeouts, including five scoreless innings on three days’ rest in the deciding Game 7 against the Toronto Blue Jays.
Comparison With Peers: Where Yamamoto Stacks Up Among Elite Starters
The aces of this era have separated themselves into a tier of their own, and to understand Yamamoto’s place you have to put his 2025 numbers next to the rest of the room. Below is a side-by-side of the five starters who finished in the top six of the Cy Young vote in either league.
| Pitcher | Team | ERA | IP | K | K/9 | BB/9 | WHIP | fWAR |
|---|---|---|---|---|---|---|---|---|
| Tarik Skubal | DET | 2.18 | 205.1 | 248 | 10.9 | 1.85 | 0.94 | 6.8 |
| Paul Skenes | PIT | 1.96 | 198.0 | 235 | 10.7 | 1.95 | 0.91 | 6.5 |
| Yoshinobu Yamamoto | LAD | 2.10 | 195.0 | 240 | 11.1 | 1.75 | 0.92 | 6.2 |
| Garrett Crochet | BOS | 2.45 | 210.0 | 252 | 10.8 | 2.10 | 1.01 | 5.9 |
| Zack Wheeler | PHI | 2.65 | 202.2 | 225 | 10.0 | 1.95 | 1.00 | 5.4 |
Yamamoto is the only pitcher in that group to combine a sub-2.00 BB/9 with a K/9 above 11. Tarik Skubal is the most polished overall starter and won the AL Cy Young, while Garrett Crochet piled up the most innings. But on a pure rate-of-elite-pitches basis, Yamamoto’s profile is the cleanest. He gives up the fewest free passes, induces the most chase, and limits the loudest contact (a 24% hard-hit rate, also the lowest in MLB among qualified starters).
The interesting comparison long-term is Skenes. The two pitchers attack hitters with similar primary weapons — a riding fastball setting up an unhittable splitter — but Skenes has an extra five inches of height and three mph on his fastball, while Yamamoto has more pitches and noticeably better command. If both stay healthy, the next half-decade of Cy Young races will run through that pair.
Impact Assessment: What He Means for the Dodgers and the Sport
The on-field impact is obvious. Yamamoto stabilized a Dodger rotation that had been chronically thin behind Clayton Kershaw and Walker Buehler in the early 2020s. With Yamamoto now anchoring a rotation that also includes Shohei Ohtani as a two-way piece, the Dodgers have run their playoff rotation odds (per FanGraphs depth charts) at over 95% in each of the last two seasons. He is the engine, not a luxury.
The off-field impact is bigger. Yamamoto’s success — together with Ohtani’s two-way dominance — has reshaped how MLB front offices value Japanese pitchers. The 2025 posting market saw four NPB pitchers receive guaranteed deals over $80 million, and Boston’s signing of right-hander Roki Sasaki was directly tied to teams’ belief that NPB starters could now be evaluated as immediate-impact MLB arms rather than projects. That is a Yamamoto effect.
He has also changed the way young pitchers train. Driveline and other player-development shops have started teaching modified versions of his throwing program. The javelin work and the long-toss-into-a-net concepts that Yamamoto brought from Japan are now standard parts of many high-level college pitching programs.
Advanced Metrics: What the Statcast Numbers Say
I do not want to drown anyone in nerd stats, but a few advanced numbers are worth pulling out because they confirm the eye test in important ways.
- xERA of 2.04 in 2025 — Statcast believes his ERA was earned, not lucky.
- Chase rate of 35.4% — top 3% of MLB pitchers, meaning hitters expand the zone against him constantly.
- Whiff rate of 31.8% — top 4% of MLB pitchers.
- Barrel rate against of 4.1% — top 6% of MLB pitchers; even when hitters connect, they rarely square him up.
- Average exit velocity allowed: 86.9 mph — among the lowest figures in baseball, similar to Garrett Crochet and Skenes.
- Extension at release: 6.9 feet — his perceived velocity plays at roughly 97.4 mph despite the 96.1 mph radar number.
The barrel rate is the most underrated stat in that list. Pitchers who limit barrels age more gracefully because they are not relying purely on missing bats; they are also winning the contact battle. That bodes well for the back half of his contract.
Health Profile and Workload Concerns
The single most asked question I get about Yamamoto is whether he can stay healthy. The 2024 IL stint was a real flag, and a small frame is a small frame. But here is the case for optimism: he has thrown 195 innings in a season exactly once in the United States and was not visibly fatigued in October. The Dodgers have leaned into a six-man rotation when feasible, and Yamamoto’s between-starts routine is more conservative than most American starters’ (he rarely throws bullpens between outings). His pitching motion also produces low elbow valgus torque relative to his velocity, per public biomechanics studies.
Will he ever throw 220 innings in a year? Probably not. But 180 to 200 innings of dominance is more valuable than 230 innings of merely good, and that is the bargain the Dodgers signed up for.
Contract and Market Value
Yamamoto’s 12-year, $325 million deal includes opt-outs after the 2029 and 2031 seasons, a $50 million signing bonus, and a posting fee paid by the Dodgers to Orix that pushed the total commitment past $360 million. At the time, it was the largest contract ever given to a pitcher. Two years in, that contract looks like a bargain.
Using public dollars-per-WAR estimates, Yamamoto’s combined 2024 to 2025 production has already returned about $90 million in surplus value above his salary. If he holds his current rate of performance, that surplus number could approach $200 million by the time his first opt-out arrives — at which point he would almost certainly opt out and reset the pitching market again.
2026 Outlook and Projections
Three things will determine whether Yamamoto wins his first Cy Young in 2026:
- Health and innings. If he hits 200 innings, he is the favorite. If he hits 170, he is in the conversation but probably loses on volume to Skubal or Crochet again.
- Splitter sustainability. Splitter-heavy pitchers historically have shorter peaks. So far the pitch is not regressing — its 2025 whiff rate (55%) was up from 2024 (52%). If it stays elite, his floor is enormous.
- Run support and bullpen. Cy Young voters claim wins do not matter, then vote like they do. The Dodger offense and bullpen will keep his win column full.
My personal projection: 17-6, 2.05 ERA, 250 strikeouts, 0.90 WHIP across 200 innings. That would be a Cy Young.
What Coaches Can Steal From His Game
I am always thinking about how big-league mechanics translate down to the youth and high school level. Yamamoto’s game has more transferable lessons than almost any modern starter. Here is what I tell pitching coaches to focus on when they ask me what to copy.
- Lead with the lower half. The hip-shoulder separation he creates is a product of his pelvis firing first. That is teachable from age 12 up.
- Use throwing as training. Yamamoto throws far and often. Long-toss programs build arm strength when sequenced correctly.
- Master one secondary before adding a fourth pitch. He spent years owning his curveball before adding the cutter. Most amateur arms try to add too much, too fast.
- Develop a true two-strike weapon. The splitter is his finisher. Every pitcher needs one putaway pitch. Our guide on baseball pitching grips covers options for every age group.
- Repeat the delivery. Command separates great from elite. Yamamoto throws 65% strikes consistently because he repeats his motion in pressure counts.
FAQ: Yoshinobu Yamamoto Stats and Career
How fast does Yoshinobu Yamamoto throw?
His four-seam fastball averaged 96.1 mph in 2025 and topped out at 99.2 mph. He sits around 95 mph with his sinker and 91 with the cutter. Late in games, he tends to hold velocity better than most starters because he conserves effort with sequencing rather than max effort.
What is Yoshinobu Yamamoto’s career ERA?
His career MLB ERA through the 2025 season is 2.39 (2.10 in 2025, 3.00 in 2024). His combined NPB and MLB career ERA is 1.83.
How big is his contract?
12 years, $325 million guaranteed, signed in December 2023. Opt-outs after years 6 and 8. The Dodgers also paid Orix a posting fee of approximately $50.6 million.
Did Yamamoto win the Cy Young in 2025?
No. He finished as a finalist in the National League and ultimately came in second to Paul Skenes. He did, however, win the World Series MVP after dominant performances in Games 2 and 7 against Toronto.
What pitch is Yamamoto’s best?
His splitter, comfortably. A 55% whiff rate makes it the best individual pitch in baseball among offerings thrown at least 400 times in 2025. He pairs it with a high-spin four-seam to create a tunnel hitters cannot resolve.
How tall is Yoshinobu Yamamoto?
5-foot-10, 178 pounds. He is one of the shortest elite starters in modern MLB history, which is a big part of why his mechanics have become a study subject for the next generation of pitchers.
How many Sawamura Awards did he win in Japan?
Three consecutive (2021, 2022, 2023). The Sawamura Award is given annually to NPB’s most outstanding starting pitcher and is roughly equivalent to a Cy Young.
How does Yamamoto compare to Shohei Ohtani as a pitcher?
Ohtani is the more electric two-way talent and his fastball plays harder, but Yamamoto is the more polished pure starter. Ohtani throws fewer innings each year because of his hitting workload; Yamamoto is the steadier rotation anchor.
Will the Dodgers keep him in the rotation long-term?
Yes. There is no scenario where Yamamoto becomes anything other than a starter. The conversation is whether they continue using a six-man rotation to manage his workload, which seems likely as long as Ohtani is also pitching.
Is Yamamoto worth a fantasy first-round pick?
For 2026 fantasy purposes, yes. He goes in the second or third round of most expert drafts because of the lingering injury concern, but the per-inning production is first-round caliber. Pair him with a more durable workhorse to balance the risk.
Final Take: A Generational Talent in His Prime
I have been writing about pitching for a long time, and I cannot remember a starter who pairs Yamamoto’s command with his stuff at his size. He is not a curiosity anymore — he is the front-line ace on the best team in baseball, and the only honest debate is whether he is the best pitcher in the National League or just the best pitcher in Los Angeles. The 2025 World Series settled the bigger question. He is here. He is not going anywhere. And the next decade of his career will be one of the more enjoyable things to follow in modern baseball.
If you are a coach trying to translate his game into something usable for your players, start with the kinetic chain, layer in the secondary work, and resist the urge to copy the splitter at the youth level — it is a high-stress pitch that needs a finished frame. If you are a fan, just enjoy what you are watching. We do not get many pitchers like this.
