Seattle Mariners
Although they have not thrown an MLB pitch in 2024, Joe Saunders threw 21,103 pitches that were tracked by the PITCHf/x system between 2007 and 2014, including pitches thrown in the MLB Regular Season and Spring Training. In 2014, they relied primarily on their Sinker (92mph), also mixing in a Fourseam Fastball (91mph), Slider (83mph), Change (82mph) and Curve (76mph).
In 2014, compared to other LHP:
Their sinker is basically never swung at and missed compared to other pitchers' sinkers and results in somewhat more groundballs compared to other pitchers' sinkers. Their fourseam fastball generates fewer whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider results in somewhat more flyballs compared to other pitchers' sliders. Their change generates a high number of swings & misses 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 17 of them in 2014) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has slightly below average velo.
