Boston Red Sox
Kyle Keller has thrown 1,051 pitches that have been tracked by the PITCHf/x system between 2019 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (94mph), Curve (79mph) and Cutter (92mph). He also rarely throws a Change (87mph).
In 2026, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has less armside movement than typical and has slightly above average velo. Their curve is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has primarily 12-6 movement. Their cutter is an extreme flyball pitch compared to other pitchers' cutters, has well above average velo, has good "rise" and has strong cutting action. Their change (take this with a grain of salt because they've only thrown 7 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
