The sight of Matt Wieters' home-run trot ending in a frenetic pile at home plate conjured memories of the 16 straight extra-inning wins the Orioles orchestrated last season.

But Thursday night's 10-inning 10-6 win over the Tampa Bay Rays — which ended with the Orioles' first walk-off grand slam in 14 years — deserves its own spot in Orioles lore.

The Orioles' first extra-inning game of 2013 came nearly a year to the date that Wieters hit a grand slam to help the Orioles to their first extra-inning win last season, a 10-4 win against the White Sox in Chicago last April 16. His blast Thursday was the Orioles' first walk-off grand slam since Harold Baines' on May 4, 1999 against the White Sox.

“Any time you get a get a walk-off and get to celebrate with your teammates, it's a good day,” Wieters said. “It's a big game. They are all big games, but any time after a loss you're able to come back and get a win the next day just to sort of try and get the momentum back going on your side, I feel it's a big game.”

The win gave the Orioles (8-7) their second series victory against the Rays this season — they also took two of three in the season-opening series at Tropicana Field — and three series wins in four early-season American League East matchups.

The victory also extended the Orioles' club-record streak of 98 consecutive regular-season wins when leading after the completion of the seventh inning, the second-longest for any club since 1961, trailing only the New York Yankees' streak of 116 in 1998 and '99.

For a club hovering around the .500 mark for most of this young season, it was a much needed win.

“It was huge for us,” said third baseman Manny Machado, who had a key bunt single in the 10th. “We've been battling pretty good the last couple of weeks, and this was a big win to get us going.”

After Nick Markakis opened Thursday's 10th inning with a single, Machado dropped a bunt that that hugged the first-base line for a base hit. Adam Jones hit a long single off the right-field wall to set the stage for Wieters, who took Brandon Gomes deep.

“Text book way to win a game is the bunt Manny put down,” manager Buck Showalter said. “I think about that as development — all the people in the farm system who don't let him not be good at that. Everybody thinks he's got a chance to be a run producer. That's something that, it's not their fault, it's our fault if they don't come up here with that.”

With the bases loaded and no outs, the Rays played with a five-man infield, so Wieters had wide gaps in the outfield and really just needed a fly ball to score the winning run.

“It's something to where your job is still to hit the ball to the outfield, whether they have four or one infielder on the infield,” Wieters said. “Your job is to hit the ball into the outfield, whether it's a sacrifice fly or you get something to fall in.”

Wieters also helped out with his arm, throwing out Rays speedster Desmond Jennings at second in the ninth inning of a tied ballgame for his seventh throwout in nine stolen base attempts against him this season.

The Rays (5-10) have seen enough of Wieters. His grand slam was his 13th career homer against Tampa Bay, his most against any club, and his .342 average against the Rays is the fourth best among active players.

The Orioles bullpen, a huge factor in the team's extra-inning success last season, allowed just one run in 4 1/3 innings, including a clutch scoreless 10th by left-hander Troy Patton (1-0), who overcame a walk and hit to strand two runners.

Orioles designated hitter Steve Pearce, who entered Thursday's game hitless in his first 13 at-bats, ended his slump in a big way, hitting a two-run homer off reliever Jake McGee to give the Orioles a 6-5 lead in the seventh inning.

“I thought I was going to be bunting in that situation, try to get the runner over to third,” Pearce said. “And I was surprised that Buck let me swing away right there. Initially, I was just trying to move the runner over. I worked the count real well, got a pitch to hammer and got it.”

The Orioles chased reigning AL Cy Young Award winner David Price from the game after six innings and then took the lead off McGee, just like they did on Opening Day in a 7-4 win at Tropicana Field.

Pearce's homer was just the fourth hit for Orioles designated hitters in 50 at-bats this season. (He added a single in the ninth.)
