San Francisco Giants
Christian Koss has thrown 7 pitches that have been tracked by the PITCHf/x system in 2025, all of them occuring in the MLB Regular Season. In 2025, they have relied primarily on their Fourseam Fastball (60mph).
In 2025, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2025) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and is straight as an arrow.
