AT&T PARK — Eduardo Nunez had no idea how dire of a situation he’d been dropped into with his new club.

The infielder was, after all, acquired in a trade with the Minnesota Twins on just Friday.

“I just found out last night that we have been struggling in the second half,” Nunez said with a smile after contributing a two-run double in the Giants’ 5-3 win on Saturday.

That key two-base hit came in the crucial fourth inning, which the Giants entered trailing 3-0. Sensing the importance of the moment, manager Bruce Bochy lifted Jake Peavy for pinch-hitter Mac Williamson with one out and runners on first and second.

Williamson walked, Nunez doubled and then Angel Pagan tied the game with a groundout to first.

“Boch managed that like a playoff game with the way we needed to win,” Peavy said. “That’s 100 percent the right call.”

Joe Panik provided the go-ahead run with a seven-inning sacrifice fly. It marked a fitting way to push across the key run after the Giants posted a .180 average with runners in scoring position over the first six games of the homestand.

In Friday’s 4-1 loss, the struggles with runners in scoring position reached a historical low. With the bases loaded in the eighth, Brandon Crawford lined into a triple play.

“It’s one of the last things you expect when you’re in that situation,” Crawford said after hitting into the first 3-3-5 triple play in baseball history.Brandon Crawfordeduardo nunezJoe PanikMLBSan Francisco GiantsWashington Nationals
