Jose Bautista hit his major league-leading 28th home run, Aaron Hill and Adam Lind also connected and the Toronto Blue Jays beat Baltimore 9-5 on Monday night for their 10th straight win over the Orioles.
Hill hit a two-run homer in the fourth, and the Blue Jays smacked two more in the fifth. Bautista hit a three-run shot and Lind added a solo blast. Toronto leads baseball with 152 homers this season, including a league-high 37 in July. The Blue Jays also lead the majors with 82 homers in home games.
All three homers came off Brad Bergesen (3-9), who has lost seven straight decisions and has not won since May 12 against Seattle. The right-hander allowed eight runs and 10 hits in five-plus innings, raising his ERA to 6.95, walked one and struck out one.
Brandon Morrow (7-6) pitched six innings to win consecutive starts for the first time this season. He allowed two runs and five hits, walked four and struck out six.
David Purcey retired Miguel Tejada with runners at first and third to end the eighth, then pitched a 1-2-3 ninth for his first career save.
The 10-game winning streak is Toronto's longest against Baltimore since a 13-game run from April 11, 1999-May 10, 2000.
The Orioles have not beaten the Blue Jays since sweeping a three-game series in Baltimore on the final weekend of the 2009 season, winning 5-4 in 11 innings to end the year.
Matt Wieters hit two homers, the first multihomer game of his career, and Luke Scott added a two-run shot for the Orioles, who have lost three straight and eight of 10 since the All-Star break.
Hill got the Blue Jays started with an RBI single in the second, and Toronto added three more in the third on Lind's RBI double and Hill's homer to center.
Bautista and Lind made it 8-0 with their fifth-inning drives before the Orioles broke through.
Wieters, who came off the disabled list Sunday, hit a two-run blast into the second deck in right off Morrow in the sixth and a solo blast to left off Casey Janssen in the eighth. He has eight homers this season.
Scott, selected AL Player of the Week after hitting four homers last week, hit a two-run shot to right off Janssen in the seventh, his 17th of the year and his fifth homer in 30 at-bats.
