WASHINGTON (AP) — A day after squandering a lead entering the seventh inning, the Royals did it again.

This time, though, Kansas City managed to rally back.

Adalberto Mondesi hit a go-ahead single in the 11th inning to help lift the Royals to a 7-4 victory over the Washington Nationals that snapped a four-game skid.

“It was big for us, especially after yesterday kind of giving up the lead (in an 8-4 loss to Cleveland) and giving it up again today,” left fielder Alex Gordon said. “I thought we could have put our heads down and took a loss, but give us credit for putting together a good inning and making something happen.”

The Nationals, who had won four straight and eight of their last nine, left 19 men on base — including the bases loaded in the sixth, seventh and 10th innings.

“I don’t think I’ve ever seen that before,” Gordon said. “Gave them chances and they didn’t get runs in. Good for us for stepping up and making the pitches count when they needed. Give our pitchers the credit for that.”

Jonny Venters (0-1), the Nationals’ fifth reliever, loaded the bases with no outs before striking out Whit Merrifield. However, Mondesi poked a single to left past a drawn-in infield to score a run. Gordon then hit a grounder to first baseman Ryan Zimmerman, whose wild throw home allowed two runs to score.

Brian Flynn (2-0) escaped a bases-loaded jam of his own creation in the 10th, and Wily Peralta worked the 11th for his second save.

Zimmerman got his 1,000th career RBI with a double in the seventh to pull Washington within 4-2. He added another off Kansas City closer Ian Kennedy in the ninth, then scored on Brian Dozier’s single. The Nationals had two on with one out, but couldn’t push across the winning run.

“Couldn’t get hits in a big moment,” Washington manager Dave Martinez said.

Trea Turner hit his fifth career leadoff home run off Kansas City starter Brad Keller, extending Washington’s franchise-record of games with a homer to 19. It was the only run the Nationals managed off Keller, who allowed six hits and five walks in 5 2/3 innings.

Kansas City scored two runs in both the third and the fifth off Washington starter Austin Voth, who lasted 4 1/3 innings in his third start of the season.
