TORONTO -- Despite being one of the major league leaders in home run allowed this season, Baltimore Orioles right-handed Chris Tillman has usually been able to limit the damage.
But Colby Rasmus' two-run homer off Tillman in the seventh inning Saturday evening, which gave the Blue Jays a 4-3 win over the Orioles at Rogers Centre, was one of the most devastating he's given up this season.
The Orioles went into the seventh-inning stretch clinging to a one-run lead, and Tillman had faced just one batter over the minimum since allowing a two-run double in the first inning.
But Rasmus' 20th homer of the season, which landed in the second deck of the right-field stands, suddenly turned the lead into a deficit as the Orioles' playoffs hopes took another hit.
An Orioles team that was 29-9 last season in one-run games is now 16-28 in them this year.
For Tillman (16-6), who became an All-Star this year and in many ways has blossomed into the club's best starter, it was the 30th homer he's allowed this season, third most in the majors.
With the loss, the Orioles (78-70) blew an opportunity to pass the New York Yankees, 5-1 losers to the Boston Red Sox earlier in the day, in the American League East and wild-card standings.
The Orioles, who went 2-for-11 with runners in scoring position, had plenty of chances to build on their lead throughout the game. They stranded five runners in scoring position and ended four innings with a runner on third base.
After Moises Sierra's two-run double in the first inning gave the Blue Jays (68-80) a 2-1 lead, Orioles third baseman Manny Machado tied the game in the third with his 14th homer of the season, a solo shot off Toronto starter Esmil Rogers.
Machado hit his 50th double of the season in the first inning, which was following by an RBI double by Chris Davis that gave the Orioles a 1-0 lead.
The Orioles took a 3-2 lead in the fourth on an RBI single by Matt Wieters that came after back-to-back one-out walks to Nick Markakis and J.J. Hardy. But the Orioles couldn't capitalize.
They also had runners at second and third with one out in the sixth and runners at the corners with two outs in the eighth but netted no runs in those innings.
Tillman threw an eight-inning complete game in the loss, but he was hurt by a leadoff walk to Sierra in the seventh. Rasmus then crushed an 84-mph changeup for the eventual game winner.
The Orioles had the tying run on base in the ninth after Nate McLouth's two-out single, but Machado weakly grounded out to the left side of the mound for the final out.
