Non-MLB
Luis Santos has thrown 836 pitches that have been tracked by the PITCHf/x system between 2017 and 2025, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2025, they have relied primarily on their Fourseam Fastball (91mph), Change (85mph) and Slider (82mph).
In 2025, compared to other RHP:
Their fourseam fastball has some natural sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers, has slight armside run and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 18 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups and results in somewhat more flyballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 13 of them in 2025) is basically never swung at and missed compared to other pitchers' sliders and is an extreme flyball pitch compared to other pitchers' sliders.
