WASHINGTON (AP) — Jorge Mateo drove in the go-ahead run with a 12th-inning single, and the Baltimore Orioles survived another shaky outing by closer Craig Kimbrel to beat the Washington Nationals 7-6 on Wednesday night and avoid being swept for the first time in nearly two years.

The Orioles blew two-run leads in the ninth and 11th. Ryan Mountcastle put Baltimore on top 5-3 with a two-run homer in the 11th off Hunter Harvey, but pinch-hitter Ildemaro Vargas hit a ground-rule double off Albert Suárez (2-0) in the bottom half to make it 5-4, and Jacob Young then tied it with a sacrifice fly.

In the 12th, Mateo led off with a base hit to score automatic runner Jordan Westburg, advanced to third on errors by third baseman Vargas and catcher Keibert Ruiz, and scored on a wild pitch by Jordan Weems (1-1).

“It was quite a game. There was a lot of stuff that happened there the last four or five innings,” Orioles manager Brandon Hyde said. “Mounty with the huge homer, Jorge with the exciting single that turned into a Little League triple. ... A lot to unpack there, but I’m definitely relieved we won the game.”
