MIAMI (AP) — Rookie Keaton Winn threw six solid innings of one-run ball and the San Francisco Giants beat the Marlins 3-1 Wednesday afternoon to win their first series in Miami since 2016.

Winn (1-3) scattered four hits and struck out four. Thairo Estrada had two hits and scored the go-ahead run in the seventh, when he raced home on a double-play grounder hit by Nick Ahmed against reliever Declan Cronin (0-2).

“Definitely nice to get that monkey off my back,” Winn said of his first victory. “Tried not to think of it but knew it would come.”

Jorge Soler and Jung Hoo Loo had two hits and scored one run each for the Giants. Matt Chapman hit an RBI double in the eighth.

The Marlins, who grounded into two double plays, dropped to an NL worst 4-15.

“These guys are fighting their tails off and working and we’re just not seeing the wins,” Marlins manager Skip Schumaker said. “That’s the most frustrating thing.”
