Non-MLB
Felix Doubront has thrown 9,100 pitches that have been tracked by the PITCHf/x system between 2010 and 2024, including pitches thrown in the MLB Regular Season, the MLB Postseason, Spring Training and Fall/Winter Ball. In 2024, they have relied primarily on their Fourseam Fastball (90mph) and Cutter (87mph), also mixing in a Sinker using a Two-seam Fastball grip (90mph), Curve (75mph) and Change (83mph).
In 2024, compared to other LHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo. Their cutter (take this with a grain of salt because they've only thrown 17 of them in 2024) is basically never swung at and missed compared to other pitchers' cutters, has good "rise" and has slightly above average velo. Their sinker using a two-seam fastball grip (take this with a grain of salt because they've only thrown 9 of them in 2024) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has less armside run than typical. Their curve (take this with a grain of salt because they've only thrown 7 of them in 2024) has an exceptional bite, is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has primarily 12-6 movement. Their change (take this with a grain of salt because they've only thrown 5 of them in 2024) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups and has slight armside fade.
