Non-MLB
Although they have not thrown an MLB pitch in 2024, Fautino De Los Santos threw 760 pitches that were tracked by the PITCHf/x system between 2011 and 2013, including pitches thrown in the MLB Regular Season and Spring Training. In 2013, they relied primarily on their Fourseam Fastball (94mph) and Change (89mph), also mixing in a Slider (82mph).
In 2013, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 16 of them in 2013) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, has an obvious tail, is an extreme flyball pitch compared to other pitchers' fourseamers and has essentially average velo. Their change (take this with a grain of salt because they've only thrown 6 of them in 2013) is thrown extremely hard, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their slider (take this with a grain of salt because they've only thrown 5 of them in 2013) has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
