Fastball velocity up to 94.7 mph in MLB
NEW YORK -- Chad Tracy notices how much baseball has changed in the 13 years since he took his last big league at-bat.
"You watch a Triple-A game, most everybody that's coming out of the bullpen left-handed or right-handed is throwing 95-plus," the Boston Red Sox manager said. "Back in the day, it was you'd get a lead and you'd get to the lower part of a bullpen and you'd see some guys coming out throwing 88."
Heading into the All-Star break, velocity is on track to set a record for the sixth straight season.
Four-seam fastballs averaged 94.7 mph through Saturday, up from 94.5 mph last year, 93.7 mph in 2021 and 91.9 mph when Major League Baseball first started tracking in 2008. The average was 94.4 mph for the first half of 2025, and this year's final figure could increase by a tick.
"Definitely expecting anybody you've never heard of to throw a 95-plus," said the New York Mets' Marcus Semien, a three-time All-Star who made his major league debut in 2013, when four-seamers averaged 92.7 mph. "Before you'd know who the guys were who were throwing 98. Now, you just expect that this new guy is probably throwing 98. So that shows how everybody's trained."
Expectations have changed. In David Auburn's "Proof," which won the 2001 Pulitzer Price for Drama, a mathematical research work is described as "streamlined: no wasted moves, like a 95-mile-an-hour fastball. It's just … elegant."
That figure no longer is notable.
Right-handed pitchers are averaging 95.2 mph in 2026, up from 95.0 mph last year. Right-handed relievers are averaging 95.6 mph.
The Triple-A average of 93.6 mph is up from 92.7 mph when tracking started at that level in 2022.
"People are learning the biomechanics of the body a lot better and it's easier to figure out why people are throwing hard," said Athletics pitcher Hogan Harris, whose four-seam average has increased from 92.6 mph as a rookie in 2023 to 95.0 mph this year. "There's so many young kids throwing hard now and then you see a lot younger people in the big leagues, so my thought is they see a guy that's throwing 100 when he's 22 and, boy, he's not going to throw 100 when it's 30, so let's get in there now."
Six pitchers are at 100 mph in average four-seam velocity led by a pair of relievers, the Athletics' Mason Miller (101.3 mph) and the Los Angeles Dodgers' Edgardo Henriquez (100.6 mph).
Milwaukee's Jacob Misiorowski, a 24-year-old starter, is averaging 100.5 mph, up from 99.3 mph as a rookie last year.
