Zac Gallen's Stats, Metrics, Game Logs, Projections & Rankings

The Arizona Diamondbacks announced that starting pitcher Zac Gallen (hamstring) left Friday's start against the Seattle Mariners due to tightness in his right hamstring. Before exiting, Gallen surrendered three runs on three hits and one walk with three strikeouts over five innings of work. He was pulled from the game after his 64th pitch in the sixth inning and relieved by Scott McGough. Although the extent of the setback won't be known until Gallen is evaluated further, the D-backs and fantasy managers should be relieved the ace isn't dealing with an injury to his throwing arm. It remains to be seen if Gallen will need a trip to the injured list, or if he'll just need his next turn in the rotation skipped, but his next start is tentatively slated for Wednesday's series finale versus the division-rival Los Angeles Dodgers. The 28-year-old workhorse right-hander owns a 3.38 ERA, 1.22 WHIP, and 35:9 K:BB over 32 frames (six starts) this year.

He is tentatively scheduled to face the St. Louis Cardinals' average offense on Sunday afternoon. Gallen should always be started, regardless of the opponent.

Arizona Diamondbacks right-hander Zac Gallen is scheduled to make his first spring Cactus League start on March 1 against the Cincinnati Reds, while right-hander Merrill Kelly will make his first start on March 8 against the Chicago Cubs. Including the playoffs, Gallen and Kelly threw 243 2/3 and 201 2/3 innings, respectively, in 2023. Kelly took some time off in the offseason before getting back to his training regiment that included range-of-motion exercises, according to manager Torey Lovullo. Because of the big workloads in their run to the World Series last year, the D-backs will make sure to take it easy on both pitchers this spring. Gallen is a low-end No. 1 fantasy starter, while Kelly profiles as more of a No. 4 to round out your fantasy rotation.
