BALTIMORE _ The Orioles mustered little offense for most of the night Wednesday, going scoreless for eight straight innings before getting an 11th-inning walk-off 5-4 win _ on a bases-loaded walk _ over the Tampa Bay Rays at Camden Yards.
No, it didn't have the excitement of most walk-off wins _ and it was one of the Orioles' uglier games of the season _ but outfielder Seth Smith drew a four-pitch walk from reliever Danny Farquhar with two outs and the bases full to end it.
The Orioles tied the score in the 11th, loading the bases with one out on singles by Chris Davis and Welington Castillo and a walk to Hyun Soo Kim. Jonathan Schoop then scored the tying run on a line-drive out to center field, scoring Davis on a sacrifice fly. Ryan Flaherty then draw a walk to load the bases again for Smith.
After scoring three runs in the second inning, the Orioles (14-6) recorded just three singles and placed just one runner in scoring position in innings three through 10.
The Orioles remained unbeaten in seven series this season (6-0-1) as they head to New York and Boston to continue an opening five weeks dominated by division games.
Rays catcher Jesus Sucre's broken-bat RBI single with two outs in the 11th off right-hander Alec Asher tied the game. Asher (1-0) put two runners on in the 11th, walking Logan Morrison and hitting Shane Peterson with a pitch before Sucre's bat shattered as he looped a ball down the right-field line to score Morrison.
The Orioles bullpen was unable to preserve a one-run lead for starter Dylan Bundy.
The Orioles entered the top of the eighth clinging to a one-run lead, but right-hander Mychal Givens, who stranded an inherited runner in scoring position in the seventh _ allowed a leadoff double to Derek Norris. Left-hander Donnie Hart then hit pinch hitter Rickie Weeks Jr. with a pitch and walked left-handed hitter Kevin Kiermaier on nine pitches.
That created a no-out, bases-loaded jam for right-hander Darren O'Day, who retired all three batters he faced, but a run scored on Brad Miller's fielder's choice groundout, a sharply hit ball on which Davis dived into the hole to keep in the infield.
Bundy recorded his fifth straight quality start to open the season, allowing just two runs � he allowed a pair of solo homers to Tampa Bay shortstop Tim Beckham � over 61/3 innings.
The Orioles had an opportunity to score the go-ahead run in the eighth inning after Manny Machado opened the inning landing on second after an infield single deep into the hole at shortstop and Beckham's ensuing wild throw into the stands.
But the Orioles came up empty. After Davis walked, struggling slugger Mark Trumbo struck out looking and Castillo hit into an inning-ending double play.
