Detroit Tigers
Although they have not thrown an MLB pitch in 2024, Nate Robertson threw 6,457 pitches that were tracked by the PITCHf/x system between 2007 and 2013, including pitches thrown in the MLB Regular Season and Spring Training. In 2013, they relied primarily on their Change (85mph) and Slider (82mph), also mixing in a Fourseam Fastball (90mph) and Sinker (87mph).
In 2013, compared to other LHP:
Their change dives down out of the zone, is slightly firmer than usual, results in somewhat more flyballs compared to other pitchers' changeups and has slight armside fade. Their slider is basically never swung at and missed compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2013) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, has essentially average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slight armside run. Their sinker (take this with a grain of salt because they've only thrown 17 of them in 2013) has heavy sinking action, has below average velo and has slight armside run.
