21. Zac Gallen
Zac Gallen came up through the St. Louis Cardinals system, but was traded to the Miami Marlins while he was still in the Minors. He would debut for Miami in June of 2019, but he was only a Marlin for seven Games before he was traded to the Diamondback at the Trading Deadline. Gallen finished the year 2-3 with a .289 ERA, and was cemented in the rotation going forward.
In the COVID-19-shortened 2020, Gallen was one of the top hurlers in the NL, going 3-2 with a 2.75 ERA and 1.111 WHIP. He was ninth in Cy Young voting, and a bright spot for a struggling Diamondbacks team. Gallen struggled last year (4-10, 4.30 ERA), but had the skills to bounce back, and boy, did he!
Arizona was not very good in 2022, but Gallen was phenemonal, finishing fifth in Cy Young Voting, while leading the NL in WHIP (0.913) and H/9 (5.9) with 192 Strikeouts and a 12-9 record. He is the top Diamondback going into 2023, and could win a Cy Young.
