Milwaukee Brewers
Rob Zastryzny has thrown 3,105 pitches that have been tracked by the PITCHf/x system between 2016 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 Cutter (85mph), Fourseam Fastball (91mph) and Change (82mph), also mixing in a Slider (80mph).
In 2026, compared to other LHP:
Their cutter has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, has sweeping cut action and is an extreme flyball pitch compared to other pitchers' cutters. Their fourseam fastball (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' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their change (take this with a grain of salt because they've only thrown 12 of them in 2026) has surprising cut action, dives down out of the zone and results in more flyballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 4 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, results in more flyballs compared to other pitchers' sliders and has less than expected depth.
