Chicago Cubs
Gavin Hollowell has thrown 2,024 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (94mph) and Slider (85mph), also mixing in a Sinker (94mph). He also rarely throws a Change (87mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, results in more flyballs 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 has some two-plane movement. Their sinker has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
