Non-MLB
Although they have not thrown an MLB pitch in 2024, Jeremy Guthrie threw 25,917 pitches that were tracked by the PITCHf/x system between 2007 and 2017, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2017, they relied primarily on their Fourseam Fastball (92mph), also mixing in a Cutter (88mph), Change (88mph) and Curve using a Knuckle Curve grip (74mph). He also rarely threw a Sinker (92mph).
In 2017, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their cutter (take this with a grain of salt because they've only thrown 8 of them in 2017) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their change (take this with a grain of salt because they've only thrown 7 of them in 2017) generates fewer whiffs/swing compared to other pitchers' changeups, is much firmer than usual and has a lot of backspin. Their curve using a knuckle curve grip (take this with a grain of salt because they've only thrown 3 of them in 2017) is basically never swung at and missed compared to other pitchers' curves, has below average velo, results in more flyballs compared to other pitchers' curves and has a sharp downward bite. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2017) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has little sinking action compared to a true sinker.
