Velocity at the very top of the scale has become more commonplace, too. There were 214 fastballs clocked at 100 MPH or better in 2008. Last season, pitchers threw 3,367 such heaters.
This is not a trend driven by a small handful of superhumans, either. Aroldis Chapman may have broken the modern mold, like Nolan Ryan, Bob Feller, and Walter Johnson did before, but in recent years more and more pitchers have followed that lead and shown capable of throwing very hard:
The number of pitchers who threw at least one pitch measured 95 MPH or greater has increased by 75% since 2008 and the number of pitchers clocking 100+ MPH has more than tripled in the same span.
Last season, 64 different hurlers crossed the century mark, led by the Twins’ Jhoan Duran’s 391 triple-digit four-seamers. Duran also led baseball in average fastball velocity at 100.8 MPH and was one of just two pitchers (Seattle’s Andrés Muńoz 100.2) to average better than 100.
