Kansas City Royals
Mike Yastrzemski has thrown 50 pitches that have been tracked by the PITCHf/x system between 2024 and 2025, all of them occuring in the MLB Regular Season. In 2025, they have relied primarily on their Change (57mph) and Knuckleball (66mph), also mixing in a Fourseam Fastball (75mph).
In 2025, compared to other LHP:
Their change (take this with a grain of salt because they've only thrown 9 of them in 2025) comes in below hitting speed, has surprising cut action and has a lot of backspin. Their knuckleball (take this with a grain of salt because they've only thrown 9 of them in 2025) flutters and floats unpredictably toward the plate. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2025) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers and is an extreme flyball pitch compared to other pitchers' fourseamers.
