Puk opened the 2024 campaign in Miami's starting rotation, but posted a 9.22 ERA and 2.63 WHIP across four starts. He subsequently landed on the injured list with shoulder fatigue, but returned in mid-May as a reliever. The 6-foot-7 southpaw fared much better in that role, dominating opposing hitters to a 1.72 ERA and 0.75 WHIP across 57.2 innings. A mid-season trade to Arizona opened up the possibility for saves, but Puk only recorded two for the D'Backs and three all season. Still, the former first-round pick was electric, even logging a 25-game stretch without permitting an earned run. While Justin Martinez enters 2025 as the presumed favorite for saves in Arizona, closing duties aren't guaranteed due to the high traffic he allows. Puk may give him some competition for the closer role, but injury risk caps the lefty's save upside since he's spent time on the IL in each of the past five seasons. Read Past Outlooks
