BALTIMORE - Brian Tallet didn't mince words or make excuses. Called upon to record his first career save, the Toronto Blue Jays left-hander didn't get the job done.

"Yeah, it was a pretty (bad) result, huh?" Tallet said after coughing up two 10th-inning runs in a 6-5 Baltimore Orioles victory over Toronto on Tuesday night. "It's what happens when you don't throw strikes early in the game, early when you get in there and let those guys get on base. Anything can happen and that's what happened."

The Blue Jays didn't make the most of early offensive opportunities and, while they took advantage of numerous mistakes by the bumbling Orioles, they couldn't put Baltimore away.

In the 10th, they ran into some old-fashioned bad luck, when right-hander Casey Janssen came up with a tight lat in his throwing shoulder and couldn't return to the mound after dispatching the Orioles on 13 pitches in the ninth.

"We're going to evaluate him, see where he's at," said acting Toronto manager Don Wakamatsu, adding that he didn't believe Janssen's injury was serious.

Wakamatsu was filling in for manager John Farrell, who remained in Toronto while being treated for pneumonia. Farrell is expected to miss the three-game series in Baltimore.

The Orioles botched their bunt defence, muffed an infield pop fly for an error, twice failed to get bunts down successfully and blew a one-run lead in the ninth inning. Yet one swing of rookie Ryan Adams' bat erased their many miscues.

"It wasn't looking good there for a minute, but we battled back," said Adams, who capped a two-run rally in the bottom of the 10th with an RBI single.

Matt Wieters led off the Baltimore 10th by drawing a walk off Tallet (0-2). Mark Reynolds walked and, after Robert Andino bunted a foul third strike, pinch hitter Jake Fox hit a game-tying single to right with Reynolds taking third.

Adams followed with a deep fly ball off the warning track in right-centre beyond a drawn-in outfield.

"In that situation, I was just trying to get the ball in the air," Adams said. "They were playing (the outfield) in and I got a pitch up. Right away, I knew it was going to be deep enough to get him in."

The victory went to Willie Eyre (1-0), whose wild pitch in the top of the 10th had put the Blue Jays ahead 5-4. That was the last in a long line of mental and physical mistakes that failed to undo the resilient Orioles.

Andino's 10th-inning bunt attempt was the second time he was unable to advance runners, and some shoddy defence in the ninth contributed to a delayed -- and undefended double steal -- as Toronto tied the game on Yunel Escobar's sacrifice fly.

"I know exactly what should have happened and didn't happen and it won't happen again, especially considering the people," said Baltimore manager Buck Showalter when asked about the wacky bunt play.

Wieters homered for Baltimore, which has won seven of nine.

The Blue Jays have lost five of six.

"You've got to take it as it comes and analyze it and you've just got to suck it up and move on to tomorrow," said Toronto's Brett Lawrie. "There's no sense in dwelling on it. You've got to come back tomorrow and keep playing."

Lawrie's sixth homer staked Toronto to a 3-0 lead in the second. After one-out walks to Edwin Encarnacion and Kelly Johnson, the native of Langley, B.C., ripped a 1-2 curveball from Jeremy Guthrie into the left-field stands.

Wieters' two-run shot cut the lead to a run in the bottom of the inning. Vladimir Guerrero led off with a single and Wieters homered to centre off Brett Cecil, his 15th.

Cecil's throwing error in the fourth allowed Baltimore to tie the game at 3. Andino doubled with two down and came around on an infield single by Nolan Reimold after Cecil threw wildly past first base.

The Blue Jays loaded the bases with none down in the fifth, but squandered the opportunity. Encarnacion bounced into a 1-2-3 double play and Johnson flied out to centre.

"There were several different opportunities to score, to do some things and the bottom line is we put ourselves in a position," Wakamatsu said. "We talked about not giving up and going to the end."
