Sorry for the AI slop but I've had ChatGPT tracking velocity.
MLB velocity update — October 1, 2026
The verdict is clearer now: velocity is still rising, and 2026 was another substantial step upward.
Average four-seam velocity finished at a record 94.8 mph, up from 94.5 in 2025 and 91.9 when pitch tracking began in 2008. That's the sixth straight season with a new record. Even more suggestive of what's coming: pitchers age 25 or younger averaged 95.9 mph.
Triple-digit pitching exploded. MLB recorded 5,687 pitches at 100+ mph, versus 3,701 in 2025 — a 54% increase in one year and more than 26 times the 214 recorded in 2008. Jacob Misiorowski alone threw 1,115 of them, smashing Jordan Hicks' previous single-season record of 673, and reached 105.5 mph. Baseball Savant's 2026 leaderboard also shows eight pitchers averaging at least 100 mph on their four-seamer among pitchers with 100+ pitches.
The biomechanics/training story increasingly looks like “raise the floor,” not merely “raise the ceiling.” MLB's analysis found that since 2008 the average pitcher's minimum fastball velocity rose 5.1 mph, while average maximum velocity rose only 1.2 mph. In other words, modern development has made pitchers capable of operating much nearer maximum effort pitch after pitch. MLB also notes the continuing role of biomechanical measurement, data-driven efficiency work and velocity-focused development throughout the minors; Triple-A four-seam velocity is already up from 92.7 mph in 2022 to 93.6 in 2026.
Bottom line: definitely rising, not plateauing. And the most striking change since our last check is the final count of 5,687 triple-digit pitches. That isn't a tiny incremental increase — it's a huge one-year jump.
The statistic I'd watch most closely in 2027 is that 95.9-mph average among pitchers 25 and younger. If that cohort replaces older, slower pitchers as you'd expect, the league-wide average has room to climb further even without anyone discovering how to throw harder than today's 104–106 mph extreme.
