Tampa Bay Rays
Jonathan Hernández has thrown 4,367 pitches that have been tracked by the PITCHf/x system between 2019 and 2025, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2025, they have relied primarily on their Slider (89mph) and Sinker (97mph), also mixing in a Change (91mph). He also rarely throws a Fourseam Fastball (97mph).
In 2025, compared to other RHP:
Their slider is thrown extremely hard and is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders. Their sinker has heavy sinking action, is thrown at a speed that's borderline unfair, has an obvious tail and results in somewhat more flyballs compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 6 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, has an obvious armside fade, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2025) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, is blazing fast and has slight armside run.
