Milwaukee Brewers
Although they have not thrown an MLB pitch in 2024, Andy Oliver threw 615 pitches that were tracked by the PITCHf/x system between 2010 and 2015, including pitches thrown in the MLB Regular Season and Spring Training. In 2015, they relied primarily on their Slider (83mph) and Fourseam Fastball (94mph).
In 2015, compared to other LHP:
Their slider (take this with a grain of salt because they've only thrown 10 of them in 2015) generates an extremely high number of swings & misses compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2015) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical, has well above average velo and has some added backspin.
