San Diego Padres
Although they have not thrown an MLB pitch in 2025, Marcos Mateo threw 1,271 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 (85mph) and Fourseam Fastball (95mph), also mixing in a Sinker (95mph). He also rarely threw a Change (89mph) and Cutter (65mph).
In 2015, compared to other RHP:
Their slider results in more flyballs compared to other pitchers' sliders and has short glove-side cut. Their fourseam fastball has some natural sinking action and has slightly above average velo. Their sinker generates a very high amount of groundballs compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers, has well above average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 3 of them in 2015) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has some natural sink.
