The Right Stuff for Zac Gallen
The Arizona Diamondbacks have a potential future ace in 24-year-old righty Zac Gallen. Making his debut for the Miami Marlins in June 2019, Gallen finished the season with a 1.6 WAR, and armed with a filthy changeup, became one of the more exciting young pitchers to appear in the major leagues last year.
This spring, Gallen will battle for the fifth spot in the Diamondbacks rotation. If he isn’t able to secure a starting role, Arizona may have him begin the season in Triple-A. Gallen could claim that rotation spot with an assist from an adjustment to one pitch, which in turn will tighten up his entire arsenal and help him become one of the tougher pitchers to face in baseball.
Though the sample is limited, Gallen did well during his first 15 big league starts. Through 80 innings pitched, Gallen produced an ERA of 2.81 (3.61 FIP), struck out 96 hitters, and posted a 2.96 K/BB ratio. Gallen also demonstrated good command last year, though his 10.8% walk rate indicated he may have struggled a bit with his control.
Gallen attacked hitters with a four-seam fastball, a knuckle curveball, a changeup, and two types of cutters: a sweeping (or hybrid) cutter and a backspinning cutter. Eric Longenhagen put a 50 FV on Gallen’s overall arsenal, with special consideration given to his changeup (55 FV). Read the rest of this entry »
