BALTIMORE -- Matt Wieters singled home the winning run with two outs in the 13th inning, part of a stunning comeback that gave the Baltimore Orioles a 7-6 victory over the Seattle Mariners on Tuesday night.
After the Mariners got the go-ahead run in the top of the 13th, the Orioles scored twice in the bottom half against Brandon League, who blew his first save opportunity in 10 chances this season.
J.J. Hardy homered and had four hits for Baltimore in his first game back from the disabled list. The Orioles, who bounced back from a 4-3 deficit in the eighth, snapped a four-game losing streak and improved to 1-17 when trailing after seven innings.
Adam Kennedy homered for the Mariners, who took the lead in the 13th on Mike Wilson's first major league hit.
In the 10th inning, both dugouts cleared after Baltimore's Felix Pie and Seattle first baseman Justin Smoak exchanged heated words. Pie was angered by a hard tag by Smoak, who had to chase down Pie after the runner reversed direction while heading toward first.
With runners on first and second in the 13th, Pie hit a wicked smash to second that bounced over the glove of Jack Wilson and into center, tying the game. One out later, Wieters delivered the game-winner.
Jeremy Accardo (2-0) got the win despite allowing a run in the top half of the 13th.
Called up from Triple-A Tacoma on Monday after the Mariners cut Milton Bradley, Wilson made his big league debut as a pinch hitter in the seventh inning. He was 0 for 3 before coming to the plate in the 13th following a leadoff double by Jack Wilson.
Mike Wilson hit a liner that glanced off the glove of Hardy at shortstop. Jack Wilson, who was running on the pitch, scored easily.
But the lead wouldn't last.
The Orioles trailed in the eighth before scoring two runs off Jamey Wright, who came in with a 1.17 ERA.
For the second time in three innings, Baltimore couldn't hold the lead.
Michael Saunders led off the ninth with a single off closer Kevin Gregg and took second on a comebacker by Ichiro Suzuki. After Chone Figgins grounded out, Smoak hit a soft liner to left that dropped in front of Pie to make it 5-all.
The Orioles trailed 2-1 before Jones hit a two-run double in the sixth, providing the Orioles with their first lead in 40 innings. But Seattle promptly went back on top in the seventh against Mike Gonzalez.
Saunders launched the rally with a two-out single that ended an 0-for-26 skid. Suzuki beat out a bunt, and Figgins followed with an RBI double. After an intentional walk loaded the bases, Koji Uehara yielded an infield hit to Olivo.
Kennedy hit a two-run homer in the second inning off Jake Arrieta, Seattle's second home run in 10 games.
Hardy made it 2-1 in the third with his first homer as an Oriole. He was activated from the 15-day disabled list before the game after missing a month with a strained left oblique.
It was only the third homer allowed by rookie starter Michael Pineda in seven starts this season.
