Chicago Cubs
Gavin Hollowell has thrown 2,812 pitches that have been tracked by the PITCHf/x system between 2022 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Fourseam Fastball (95mph) and Slider (83mph), also mixing in a Sinker (95mph) and Change (87mph).
In 2026, compared to other RHP:
Their fourseam fastball has heavy sinking action, generates more whiffs/swing compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their slider sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders and generates fewer whiffs/swing compared to other pitchers' sliders. Their sinker (take this with a grain of salt because they've only thrown 9 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has well above average velo. Their change (take this with a grain of salt because they've only thrown 9 of them in 2026) has an obvious armside fade, dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
