Matt Stairs and Gregg Zaun each hit two-run homers, A.J. Burnett pitched seven sharp innings and the Toronto Blue Jays beat slumping Seattle 6-4 on Sunday, sending the Mariners to their season-high ninth consecutive loss. Seattle, which begins a three-game series with considerable playoff implications at the New York Yankees on Monday, has not won since Aug. 24 at Texas, a victory that put the Mariners a season-high 20 games over .500. The Mariners began the day 6 1/2 games back of the Los Angeles Angels in the AL West and two games back of the Yankees in the wild-card race.

The nine-game losing streak is Seattle's longest since an 11-game skid from Aug. 10-20, 2006.

Toronto has won seven of its past 10 and, at 70-66, is a season-high four games over .500.

Burnett (8-7) retired the first ten batters in order and struck out five of the first six. He allowed three runs and four hits, walked one and struck out seven to win for the first time in three starts.

Left-hander Scott Downs pitched to two batters in the eighth and right-hander Brian Wolfe finished the inning before Casey Janssen threw a perfect ninth for his fifth save in nine opportunities.

Toronto took a 3-0 lead in the second against Seattle right-hander Jeff Weaver when Zaun followed an RBI single by Aaron Hill with his second homer in as many days.

Stairs made it 5-0 with a two-out, two-run drive in the third.

Seattle scored twice in the fourth on an RBI single by Raul Ibanez and an RBI groundout by Adrian Beltre that brought Jose Guillen all the way around from second base.

Kenji Johjima's seventh-inning sacrifice fly made it 5-3, but Toronto added a run in the bottom of the inning on Hill's RBI single.

Ibanez, who finished 2-for-4, capped the scoring with an RBI single in the eighth.

Weaver (6-11) allowed five runs and eight hits in three-plus innings. He walked one, struck out one and lost for the second time in three starts against Toronto this season.

Hill finished 3-for-4 with two RBIs.
