Houston Astros
Although they have not thrown an MLB pitch in 2025, Luis Guillorme threw 80 pitches that were tracked by the PITCHf/x system between 2020 and 2024, all of them occuring in the MLB Regular Season. In 2024, they relied primarily on their Fourseam Fastball (60mph).
In 2024, compared to other RHP:
Their fourseam fastball comes in below hitting speed, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is straight as an arrow and generates more whiffs/swing compared to other pitchers' fourseamers.
