Miami Marlins
Although they have not thrown an MLB pitch in 2024, Chris O'Grady threw 694 pitches that were tracked by the PITCHf/x system between 2017 and 2018, all of them occuring in the MLB Regular Season. In 2018, they relied primarily on their Cutter (82mph) and Fourseam Fastball (88mph), also mixing in a Change (81mph). He also rarely threw a Slider (74mph).
In 2018, compared to other LHP:
Their cutter comes in below hitting speed, has heavy sink, has extreme cut action and results in more flyballs compared to other pitchers' cutters. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has below average velo. Their change (take this with a grain of salt because they've only thrown 14 of them in 2018) is basically never swung at and missed compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups and has slight cut action. Their slider (take this with a grain of salt because they've only thrown 7 of them in 2018) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone and has exceptional depth.
