It had been nearly 18 months since Brian Matusz pitched a game with the precision of the one he threw against the Toronto Blue Jays on Thursday night.

During Matusz's dubious losing streak – the longest in the major leagues – the Orioles left-hander has shown flashes of revival, but those games never ended with a complete package of optimism. Orioles manager Buck Showalter has waxed about Matusz's marked improvement in 2012, but the results haven't been there.

But on Thursday night, against a lineup known to feast on left-handed pitching, Matusz recorded his first quality start since the final week of the 2010 season and the Orioles hit a pair of pivotal eighth-inning homers as they completed a three-game sweep of the Blue Jays with a 5-2 win at Camden Yards in front of an announced 13,725.

"He pitches like that, he's going to get all the wins he wants," Showalter said of Matusz.

"He's throwing the ball great in his work days and he's got a good frame of mind, and we all know how close he was to having some good outings," Showalter added. "There wasn't a lot of firm contact. This is a club that's playing as good as anybody in the American League coming into this series."

With the win, the Orioles (12-7) are five games over .500 for the first time since their 6-1 start to last season. They not only completed their first three-game sweep of Toronto since Sept. 13-15, 2010, but also kept a share of the AL East lead with the Tampa Bay Rays.
