Arizona Diamondbacks starting pitcher Zach Gallen was placed on the 10-day injured list July 13, 2026, dealing a blow to a rotation already ranked 12th in MLB ERA. The move comes as the team sits 9th in the National League with a 49-47 record despite a current four-game winning streak.
Gallen left his July 12 start against the Los Angeles Dodgers after 5.1 innings with right forearm tightness. The 30-year-old right-hander underwent imaging that revealed no structural damage, but the Diamondbacks opted for caution with their ace. Gallen owns a 3.88 ERA and 1.02 WHIP through 21 starts this season.
Losing Gallen weakens a pitching staff that's already leaned heavily on its bullpen. The Diamondbacks rank 26th in starter innings pitched this season. With the NL Wild Card race tightening, Arizona's ability to maintain its current form without Gallen will hinge on depth starters like Ryne Nelson and Madison Bumgarner.
Arizona begins a critical seven-game homestand Friday against NL West rivals San Diego and San Francisco. The Padres currently hold the third Wild Card spot, 2.5 games ahead of the Diamondbacks. Gallen's absence means the bullpen must shore up its 4.23 ERA, fourth-highest in baseball during July.
The Diamondbacks last fell 5-3 to the Dodgers on July 12 despite Ketel Marte's two-run homer. Their four-game win streak includes sweeps of Colorado and Cincinnati, improving to 27-22 at Chase Field this season.
Manager Torey Lovullo said the right-hander will rest until at least July 24, with a potential rehab assignment in Triple-A Reno. Arizona's rotation currently features three pitchers with under 100 MLB starts combined. Gallen's timetable remains fluid pending further evaluation.
The injury continues a challenging season for Gallen, who missed 10 days in June with a left hamstring strain. Despite the health setbacks, he ranks among NL leaders in innings pitched (122.1) and opponent batting average (.238).
