Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Randy Williams threw 932 pitches that were tracked by the PITCHf/x system between 2009 and 2011, including pitches thrown in the MLB Regular Season and Spring Training. In 2011, they relied primarily on their Fourseam Fastball (94mph) and Sinker (93mph), also mixing in a Cutter (87mph). He also rarely threw a Change (82mph) and Curve (74mph).
In 2011, compared to other LHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their sinker results in somewhat more flyballs compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink and results in more flyballs compared to other pitchers' cutters. Their change (take this with a grain of salt because they've only thrown 6 of them in 2011) has an obvious armside fade, is an extreme flyball pitch compared to other pitchers' changeups, generates fewer whiffs/swing compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 6 of them in 2011) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has a sharp downward bite and has slightly below average velo.
