Zac Gallen's Potential Free Agent Destinations: Orioles, Giants, Athletics Emerge

Arizona Diamondbacks RHP Zac Gallen, a proven top-of-the-rotation force despite a 4.83 ERA in 2025, is a key MLB free agent. Potential landing spots include the Baltimore Orioles, who seek an ace to bolster their struggling rotation (26th in MLB in opponent batting average); the San Francisco Giants, aiming to strengthen their rotation (tied for 23rd in WHIP) with a trio alongside Webb and Ray; and the Oakland Athletics, who, with a strong young core, need an ace to anchor their 27th-ranked ERA pitching staff. Gallen averaged a 3.20 ERA and 1.09 WHIP from 2022-24 and led Arizona to the 2023 NL pennant.
