FanGraphs: Carruth: Fastball Losses

As Mrs. Delaviour (French for dicknose) said to me in high school…“You’re the most negative person I’ve ever met.” So…to answer that here’s the Fastball Gains.

Looking at the list from the other end, however – that is, from the pitchers that lost the most speed on average on their fastballs – produces more starters. Whether because starters will get more innings even when injured, a usual byproduct of diminished fastball speed, or some other cause is open for speculation, but the results are definitely interesting.

As promised, a list of the biggest drops in fastball speed from 2009 to 2008. A minimum of 50 innings pitched in each season was needed to qualify.
