Boston Red Sox
Garrett Richards has thrown 14,147 pitches that have been tracked by the PITCHf/x system between 2011 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Fourseam Fastball (94mph) and Slider (88mph), also mixing in a Curve (80mph). He also rarely throws a Sinker (95mph).
In 2021, compared to other RHP:
His fourseam fastball has heavy sinking action, is straight as an arrow, generates a very high amount of groundballs compared to other pitchers' fourseamers and has slightly above average velo. His slider is thrown extremely hard, has exceptional depth and results in somewhat more groundballs compared to other pitchers' sliders. His curve has an exceptional bite, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. His sinker (take this with a grain of salt because he's only thrown 18 of them in 2021) has surprisingly little armside run, generates more whiffs/swing compared to other pitchers' sinkers, has well above average velo, results in somewhat more flyballs compared to other pitchers' sinkers and has some natural sinking action.
