San Francisco Giants
Although they have not thrown an MLB pitch in 2024, Jeremy Affeldt threw 7,694 pitches that were tracked by the PITCHf/x system between 2007 and 2015, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2015, they relied primarily on their Sinker (91mph) and Curve (75mph), also mixing in a Splitter (87mph). He also rarely threw a Fourseam Fastball (93mph).
In 2015, compared to other LHP:
Their sinker is basically never swung at and missed compared to other pitchers' sinkers, generates a very high amount of groundballs compared to other pitchers' sinkers and has some natural sinking action. Their curve has an exceptional bite, has sweeping glove-side movement and results in somewhat more flyballs compared to other pitchers' curves. Their splitter is thrown extremely hard, has some natural sink to it and has slight armside fade. Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2015) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has slight armside run and has slightly above average velo.
