Minnesota Twins
Grant Hartwig has thrown 2,906 pitches that have been tracked by the PITCHf/x system between 2021 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Sinker (93mph), Slider (81mph) and Cutter (90mph), also mixing in a Change (85mph).
In 2026, compared to other RHP:
Their sinker has heavy sinking action and has an obvious tail. Their slider (take this with a grain of salt because they've only thrown 18 of them in 2026) is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone and has below average velo. Their cutter (take this with a grain of salt because they've only thrown 16 of them in 2026) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has little cutting action, has slightly above average velo and has some natural sink. Their change (take this with a grain of salt because they've only thrown 9 of them in 2026) dives down out of the zone, generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual.
