Zac Gallen Named Diamondbacks Opening Day Starter

Zac Gallen will make his fourth consecutive Opening Day start for the Diamondbacks against the Dodgers on March 26. He assumes the role after Merrill Kelly was ruled out due to a back injury. Gallen, who re-signed with Arizona this spring, holds a 1-2 record and 6.59 ERA in previous Opening Day starts. He ties Brandon Webb for the second-most Opening Day starts in franchise history, trailing only Randy Johnson's six. Gallen posted a 4.83 ERA over 192 innings in 2025.
