2022 Player Outlook
Gallen was a strong source of strikeouts in 2021, but he was a massive victim of the long ball. Truly it’s surprising he even pitched at all in the second half of the season as he was diagnosed with a hairline fracture in his arm early on that was thought to be more serious. Regardless he threw 121.1 innings and collected 139 strikeouts, but he did allow 3.63 BB/9 and 1.41 HR/9. With the Diamondbacks not projecting to be a great team in 2022, he likely won’t be a reliable source for wins. But he’s the best pitcher on the team and has the ability to hit 200 strikeouts if he stays healthy.
