Non-MLB
Although they have not thrown an MLB pitch in 2024, Luis Sardinas threw 24 pitches that were tracked by the PITCHf/x system between 2016 and 2017, all of them occuring in the MLB Regular Season. In 2017, they relied primarily on their Fourseam Fastball (81mph), also mixing in a Change (75mph) and Curve (70mph).
In 2017, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 10 of them in 2017) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 3 of them in 2017) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action and results in more flyballs compared to other pitchers' changeups. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2017) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has slight glove-side movement.
