Robert Gsellman has thrown 6,656 pitches that have been tracked by the PITCHf/x system between 2016 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Sinker (92mph) and Slider (88mph), also mixing in a Change (85mph) and Curve (81mph). He also rarely throws a Fourseam Fastball (91mph).


In 2024, compared to other RHP:
Their sinker generates more whiffs/swing compared to other pitchers' sinkers, results in somewhat more groundballs compared to other pitchers' sinkers and has slight armside run. Their slider is thrown extremely hard, has primarily 12-6 movement, results in more flyballs compared to other pitchers' sliders and has less than expected depth. Their change generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite, is slightly harder than usual and has primarily 12-6 movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 10 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has slight armside run and has slightly below average velo.
