Shohei Ohtani’s fastest pitch in Major League Baseball is 101.7 mph, a four-seam fastball thrown on June 28, 2025 against the Kansas City Royals. The pitch came in just his third start back from his second elbow surgery, which is the part that made jaws drop: most pitchers spend a year after an elbow operation hoping their old velocity returns. Ohtani set a new personal record with his rebuilt arm still in ramp-up mode.
And here’s the twist: 101.7 isn’t even the hardest he’s ever thrown. Ohtani hit 102 mph at the 2023 World Baseball Classic and 102.5 mph (165 km/h) in Japan, a mark that stood as the fastest pitch in NPB history for years. Strangest of all, his two hardest pitches on record, the WBC heater and the MLB-best 101.7, were both thrown to the same unlucky hitter.
The chart below covers the full velocity story: every one of his fastest pitches by level, the anatomy of the record throw, how his heat has survived two elbow reconstructions, how he compares to history’s hardest throwers, and the seven-pitch arsenal built around the fastball. Take a look, then we’ll break it all down.

The record: 101.7, on a rebuilt elbow
Shohei Ohtani’s fastest MLB pitch, 101.7 mph, arrived under circumstances that made it more than a radar-gun trivia answer. It was June 28, 2025, his third start after nearly two years away from pitching following his second elbow operation, with the Dodgers using him as a two-inning opener. Runners on first and second, one out, 0-2 count: Ohtani reached back and fired a four-seamer inside to Vinnie Pasquantino, who beat it into an inning-ending double play. Ohtani smiled his way back to the dugout; his manager admitted afterward he hadn’t expected triple digits at all, let alone a career record. The pitch beat his previous MLB best of 101.4, set back in September 2022, and stood as the fastest thrown by any Dodger that season.
The Pasquantino curse, and the harder ones abroad
The 101.7 is his MLB record, not his life record, and the trivia gets better from there. Pitching for Team Japan at the 2023 World Baseball Classic, Ohtani struck out a Team Italy first baseman with a 102 mph fastball. That first baseman: Vinnie Pasquantino. The two hardest pitches of Ohtani’s professional career have been thrown at the same human being, on two continents, in two different uniforms, a coincidence Pasquantino has joked he’d like to discuss with him personally. The absolute peak came earlier still: 165 km/h, about 102.5 mph, for the Nippon-Ham Fighters in 2016, a mark that stood as the fastest pitch in Japanese professional baseball history until 2023. And the legend started even before that, when an 18-year-old Ohtani touched 160 km/h as a high schooler, a velocity no Japanese prep pitcher had ever recorded.
The heat that surgery couldn’t take
The most remarkable row on Ohtani’s velocity chart isn’t a number, it’s the trend line refusing to bend. Elbow reconstructions routinely shave velocity from pitchers; Ohtani has had two, and his peaks after each surgery exceeded the ones before. His post-Tommy John years produced the 101.4 and the WBC 102; his return from the 2023 hybrid repair produced the 101.7 within three starts, and his four-seamer has sat in the 98 mph range as a full six-inning starter in 2026, fueling the best ERA of his career. Whether that’s testament to the surgical techniques, his rehab, or simply Ohtani being Ohtani, no one has come back from two elbow operations throwing career-best heat, until him.
Fast, but that’s not the point
For context, Ohtani doesn’t own the sport’s velocity crown, Aroldis Chapman’s 105.8 mph remains untouchable, and the hardest throwers are almost all relievers who empty everything into one inning. Ohtani’s triple digits come in a different context entirely: as a starter, pacing himself across six innings and 100-plus pitches, on days when he also bats leadoff. His average fastball runs about four mph above the league norm, and it fronts a seven-pitch arsenal, headlined by his signature sweeper and a bottom-dropping splitter, that turns the velocity from a stunt into strikeouts. Plenty of pitchers have thrown 101. None of them was also leading his team in home runs that afternoon.
Final Word
Shohei Ohtani’s fastest pitch: 101.7 mph in MLB, thrown June 28, 2025 in just his third start back from elbow surgery; 102 mph at the 2023 World Baseball Classic; and 102.5 mph (165 km/h) in Japan, a national record for years, with both of his two hardest career pitches somehow aimed at Vinnie Pasquantino. The heat has now survived a decade, two elbow reconstructions, and a workload no pitcher in a century has attempted. The radar gun keeps saying what the rest of his career says: the normal limits don’t apply.
