Pitching style Jackson is one of a minority of MLB starting pitchers who relies almost exclusively on two pitches, a mid-90s fastball and an effective power slider. His four-seam fastball has good velocity, averaging about 95 mph. He also has a two-seamer with similar velocity. His primary weapon against right-handed hitters is a hard slurve in the upper 80s. Against left-handed hitters, he often uses a changeup (85–89) and occasionally a curveball (78–81).
