Luke Scott singled in the winning run in the 11th inning, and the Baltimore Orioles ended a 12-game losing streak against the Toronto Blue Jays with a 4-3 victory Monday night.

Brian Roberts homered for the Orioles, now 1-12 against Toronto this season. Those 12 losses came before manager Buck Showalter arrived in Baltimore and rejuvenated a 32-73 team that has gone 24-15 since his debut on Aug. 3.

Nick Markakis led off the 11th with a single off Brian Tallet (2-6). After a groundout by Ty Wigginton advanced Markakis, Scott lined a single to center that easily brought home the decisive run.

David Hernandez (7-8) got two outs to earn the win.

Baltimore won despite going 2 for 11 with runners in scoring position and stranding 15.

The game attracted a meager crowd of 9,882, in part because it was played while the Baltimore Ravens faced the New York Jets in a televised NFL game. The smallest gathering in the 19-year history of Camden Yards is 9,129.

Edwin Encarnacion homered for the Blue Jays, extending Toronto's streak of successive games with a home run to 15 — the team's longest such run since July 2000. It was the 14th homer of the season for Encarnacion, who came off the disabled list Monday after being sidelined with a sprained left wrist.

Orioles starter Brian Matusz pitched only one inning before leaving with a bruise on the back of his upper arm, an injury that occurred when he was struck by a line drive off the bat of Yunel Escobar. The rookie had won his previous four starts.

Rick VandenHurk came in and retired the first 12 batters before Encarnacion hit a 1-1 pitch into the left-field seats leading off the sixth. VandenHurk allowed one run and two hits in 5 1-3 innings.

Baltimore led 3-1 before the Blue Jays rallied in the eighth. Two singles and a grounder put runners at second and third with two outs for Escobar, who grounded a two-run single up the middle off Jim Johnson.

It would be Toronto's last hit.

After Matusz ended his stint by striking out Lyle Overbay with two outs and runners on second and third, Roberts got the Orioles started with his 13th career leadoff homer, a drive to left on a 3-2 pitch from Marc Rzepczynski.

Baltimore made it 2-0 in the second when Adam Jones doubled and scored on a chopper down by the third-base line by Brandon Snyder, the rookie's first major league hit and RBI.

Baltimore went up 3-1 in the seventh. With the bases loaded and two outs, Shawn Camp hit Jones with a pitch to force in a run.

NOTES: Roberts was hit by a pitch near his right knee in the eighth inning and replaced in the ninth. ... Toronto hired Jay Sartori as assistant general manager Monday. Sartori was most recently director of baseball operations for the Washington Nationals. ... VandenHurk's outing was the longest by an Oriole this season. ... RHP Kyle Drabek, son of former National League Cy Young Award winner Doug Drabek, joined Toronto in anticipation of his major league debut Wednesday night against the Orioles. "The consistency with my delivery has come a long way," Kyle Drabek said. "Everything is the same. I'm not tipping my pitches."
