Reviewing Starting Pitcher Fastball Velocity Gainers & Decliners — Apr 6, 2026

In early April, I took a look at starting pitchers who had enjoyed increased fastball velocities, and those who had suffered declines. Since velocity is highly correlated with both strikeout rate and ERA, velocity is an important metric to track during the season. Identifying early season risers could help pinpoint breakouts, while decliners could help you avoid busts. But are the early gains actually sustainable and do the losses stick? Let’s review the pitchers and see what happened the rest of the year.
