Zac GallenARI · SP

2026 review

Zac Gallen was a rotation piece for ARI whose stuff got hit hard: his 46.3 Hard% over 369 BBE was the 2nd highest of 517 pitchers with 100+ BF, and his 13.6 K% over 472 BF was the 16th lowest of 517 pitchers with 100+ BF. He posted a 6.07 ERA and 1.55 WHIP in 105.1 IP over 22 games and 20 GS, with 35 BB and 64 SO across 472 BF, going 3-9. Right elbow inflammation put him on the 15-day IL Jul 12 retroactive to Jul 9, and after a transfer to the 60-day IL Aug 3 and a rehab assignment Aug 30 he was activated Sep 9, missing 62 regular-season days in that stint. Drafted at NFBC ADP rank 220, he finished 1465th of 1472 in the TDK LABS 5x5 value rank, 1245 spots below, and 229th of 236 starting pitchers. His 6.07 ERA ran 0.57 below his 6.64 xERA over 472 BF. His best month was Apr at a 2.19 ERA in 24.2 IP against an 8.33 ERA in 27.0 IP in Jun. By Sep 24 the TDK LABS card had him shifted from the rotation to the bullpen, describing him as a low-strikeout long reliever with little chance at finishing games.
