PHOENIX — Zac Gallen returned from a hamstring injury that sidelined him a month to pitch one-hit ball over six innings in the Arizona Diamondbacks' 3-0 victory over the Oakland Athletics on Saturday.
Ketel Marte had three hits and drove in a run to help the Diamondbacks snap a three-game losing streak.
Galen (6-4) left his previous outing May 30 at the New York Mets after facing one batter. He was diagnosed with a strained right hamstring and was placed on the injured list.
''He was landing every pitch that he possibly could. It was exactly what we needed," Diamondbacks manager Torey Lovullo said. "It's inspiring, when you know what he's done and step right in and do what he did for us today.''
Gallen threw 77 pitches and 50 for strikes. He walked one and struck out seven. The only hit against him was Brent Rooker's two-out single in the first. The only other Oakland hit came in the seventh.
Gallen had a similar injury in 2021 and said he wasn't satisfied with his return from it that time.
''I physically felt good but mentally, wasn't really ready to pitch,'' he said about the injury three years ago. ''I challenged myself to do better this time.
"I hadn't thought about my hamstring since the first time I got back on the mound (in rehab). Since then I haven't felt anything,''
