Boston Red Sox
Tanner Houck has thrown 8,070 pitches that have been tracked by the PITCHf/x system between 2020 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (95mph) and Slider (84mph), also mixing in a Change (90mph) and Fourseam Fastball (95mph). He also rarely throws a Cutter (91mph).
In 2025, compared to other RHP:
Their sinker has heavy sinking action, has well above average velo and has slight armside run. Their slider sweeps across the zone and has exceptional depth. Their change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and generates fewer whiffs/swing compared to other pitchers' changeups. Their fourseam fastball has heavy sinking action, is an extreme flyball pitch compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their cutter (take this with a grain of salt because they've only thrown 19 of them in 2025) has heavy sink, results in more flyballs compared to other pitchers' cutters, has little cutting action and has slightly above average velo.
