Toronto Blue Jays
Although they have not thrown an MLB pitch in 2025, Tyler Heineman threw 15 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 (59mph).
In 2024, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2024) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has some added backspin.
