Washington Nationals
Although they have not thrown an MLB pitch in 2024, Jonny Venters threw 4,439 pitches that were tracked by the PITCHf/x system between 2010 and 2019, including pitches thrown in the MLB Regular Season and Spring Training. In 2019, they relied primarily on their Sinker (93mph), also mixing in a Curve using a Knuckle Curve grip (85mph) and Fourseam Fastball (93mph). He also rarely threw a Change (87mph).
In 2019, compared to other LHP:
Their sinker has heavy sinking action, generates more whiffs/swing compared to other pitchers' sinkers, has well above average velo and has less armside run than typical. Their curve using a knuckle curve grip is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has little depth. Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 5 of them in 2019) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
