Cleveland Guardians
Although they have not thrown an MLB pitch in 2025, Jeff Beliveau threw 1,349 pitches that were tracked by the PITCHf/x system between 2012 and 2018, including pitches thrown in the MLB Regular Season and Spring Training. In 2018, they relied primarily on their Fourseam Fastball (90mph) and Curve (75mph). He also rarely threw a Change (82mph) and Cutter (84mph).
In 2018, compared to other LHP:
Their fourseam fastball results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. Their curve is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves, is basically never swung at and missed compared to other pitchers' curves, has sweeping glove-side movement and has a sharp downward bite. Their change (take this with a grain of salt because they've only thrown 4 of them in 2018) generates an extremely high number of swings & misses compared to other pitchers' changeups and is an extreme flyball pitch compared to other pitchers' changeups. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2018) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has little cutting action and has slightly below average velo.
