McLouth began the inning with a walk and moved to third on J.J. Hardy's single before Teagarden plated the go-ahead run. Another run would score on a fielder's choice to give the Orioles the 4-2 lead. It is the Orioles 14th straight extra inning win.
Mariners starter Erasmo Ramirez held the Orioles to just two hits over eight innings. In the ninth, he gave up hits to pinch hitter Ryan Flaherty and McLouth before being replaced by closer Tom Wilhelmsen. Hardy bunted the runners into scoring position and Chris Davis followed with a single to tie the game at two, handing Ramirez a no decision.
Jake Arrieta was called on with one out in the 6th, and the Orioles bullpen didn't allow a run over the final 12 2/3 innings. Steve Johnson threw three innings and Tommy Hunter threw two innings before they could finally get the ball to Johnson with the lead.
There were plenty of times for both teams to end the game in extra innings.
The Orioles had a chance to go ahead in the 11th when Steve Tolleson hit a pinch-hit single to lead off the frame. After a sac bunt, Hardy drew a walk. After Josh Kinney struck out Xavier Avery, he hit Adam Jones with a pitch to load the bases, but Matt Wieters struck out to end the threat.
Dustin Ackley doubled to lead off the bottom of the 12th, but didn't move any farther as Pedro Stropp retired the next three hitters.
J.J. Hardy hit a one-out single in the 16th, moved to second on a balk and third on a groundout, but Adam Jones grounded out to short and the score remained tied.
In the bottom of the 16th, Miguel Olivo led off with his third walk of the game (and seventh of the season). Carlos Triunfil bunted him to second, but Ackley grounded to short and Franklin Gutierrez fouled out to right.
In the 17th, Mark Reynolds was hit by a pitch with one out. Manny Machado's single put runners on first and third. Pinch hitter Lew Ford hit a smash, but Triunfil gloved it for the second out and Omar Quintanilla lined out to second to end the threat.
In the bottom of the inning, Kyle Seager doubled to deep right, but wouldn't get any farther.
