TORONTO -- Jose Bautista hit a tiebreaking two-run homer in the eighth inning as the Toronto Blue Jays defeated the Baltimore Orioles 4-2 on Saturday afternoon to extend their winning streak to 10 games.

With Rajai Davis on board, Bautista turned on a pitch from reliever Darren O'Day for his 16th homer of the season. Reliever Darren Oliver (3-1) pitched one inning for the win and Casey Janssen worked the ninth for his 17th save.

Toronto (37-36) moved over the .500 mark for the first time this season while Baltimore fell to 42-33.

The 10-game streak is the longest active winning streak in the major leagues. Toronto last won 10 in a row late in the 2008 season.

Toronto scratched out a run in the first inning when Melky Cabrera led off with a walk and moved to third on an Adam Lind single. Orioles starter Miguel Gonzalez (5-3) threw a wild pitch that allowed Cabrera to come home with the game's first run.

Cabrera saved a run in the next frame with a strong defensive effort.

With two outs and Chris Davis on third base, Travis Ishikawa hit a flare to shallow left field. Cabrera -- who has had hamstring problems this season -- showed some nice range by making a nice running catch.

Toronto starter Chien-Ming Wang showed off his defensive skills in the third, using his quick reflexes to snag a liner and then doubling off Ryan Flaherty at first base. Nate McLouth followed with a slicing drive to deep left that Cabrera tracked down at the warning track.

Baltimore made it a 1-1 game in the fifth inning. Davis reached on an error by second baseman Emilio Bonifacio.

Davis moved to second on a J.J. Hardy groundout and scored when Ishikawa singled up the middle. Ishikawa moved to second on a wild pitch but was stranded when Taylor Teagarden grounded out.

Toronto restored its lead in a hurry.

In the bottom of the fifth, Izturis smacked the first pitch from Gonzalez over the wall in right field. The solo shot was his fifth homer of the season.

Wang needed only five pitches to get through the sixth inning as the Orioles hit three straight ground-ball outs. The highlight play came from first baseman Edwin Encarnacion, who made a great diving stab to deny Manny Machado a hit.

The Rogers Centre crowd of 43,261 gave Wang a standing ovation when he was pulled after getting the first out in the seventh inning. He allowed five hits, one unearned run and struck out two batters.

Aaron Loup came on in relief and hit Davis with a pitch. Loup was promptly replaced by Neil Wagner, who threw a wild pitch to Hardy that allowed Davis to move to second base.

Davis moved to third on a groundout by Hardy. Wagner got Ishikawa to fly out to end the inning.

Teagarden made it a 2-2 game in the eighth inning when he hit a solo homer off Oliver. McLouth reached on an infield single but was caught stealing and Machado fanned for the third out.

Munenori Kawasaki reached on a one-out single in the bottom half of the frame. He was forced out at second when Davis hit into a fielder's choice.

Bautista followed with his homer that barely cleared the wall by the left-field foul pole.
