Philadelphia Phillies
Although they have not thrown an MLB pitch in 2025, Chad Billingsley threw 18,205 pitches that were tracked by the PITCHf/x system between 2007 and 2015, including pitches thrown in the MLB Regular Season and Spring Training. In 2015, they relied primarily on their Fourseam Fastball (92mph) and Sinker (91mph), also mixing in a Cutter (88mph), Change (85mph) and Curve (77mph). He also rarely threw a Slow Curve (67mph).
In 2015, compared to other RHP:
Their fourseam fastball has much less armside movement than typical, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their sinker has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. Their cutter has heavy sink, has extreme cut action and results in somewhat more groundballs compared to other pitchers' cutters. Their change is basically never swung at and missed compared to other pitchers' changeups, results in somewhat more groundballs compared to other pitchers' changeups and has some natural sink to it. Their curve has an exceptional bite, generates fewer whiffs/swing compared to other pitchers' curves, results in many more groundballs compared to other pitchers' curves and has slight glove-side movement. Their slow curve (take this with a grain of salt because they've only thrown 17 of them in 2015) is a real yakker that's separated from their other curveball due to its big drop and slow speed.
