Edwin Encarnacion hit his third home run in three games, Henderson Alvarez won for the first time since August and the Toronto Blue Jays beat the Seattle Mariners 7-2 Sunday.

Jeff Mathis added a two-run homer as Toronto broke open a close game with a five-run eighth inning.

Chone Figgins and Miguel Olivo hit solo homers for the Mariners, who lost their second straight.

Encarnacion had a solo homer in Toronto's 9-5 defeat Friday and hit his fourth career grand slam in Saturday's 7-0 win. He went deep again in the finale, lacing a tiebreaking drive to left in the sixth off Seattle's Jason Vargas. Encarnacion's homer was his team-leading seventh.

Encarnacion, who walked in his first two plate appearances Sunday, was hit on the left arm by Steve Delabar in the eighth, responding with a long stare at the mound.

Charlie Furbush replaced Delabar before Jose Bautista, who had led off with a single, and Encarnacion pulled off a double steal. Pinch hitter Rajai Davis was intentionally walked before Brett Lawrie hit a two-run double. One batter later, Davis scored on an errant pickoff throw by Olivo. Colby Rasmus struck out before Mathis homered into the second deck in left, his second.

Alvarez (1-2) allowed one run and six hits in six-plus innings to win for the second time in 15 major league starts. Alvarez, whose only other victory came at Baltimore last Aug. 31, walked a career-high three and struck out one.

The Mariners jumped in front early when Figgins drilled Alvarez's sixth pitch of the game over the wall in right, his second leadoff shot this season.

Vargas (3-2) held Toronto hitless until Eric Thames' two-out double in the fourth, an otherwise routine fly ball that dropped in front of Figgins in left. The hit moved Encarnacion, who had walked, up to third base, but Vargas escaped when Figgins caught Lawrie's fly ball for the third out.

The Blue Jays broke through against Vargas in the fifth. Rasmus led off with a single, advanced to second on a grounder and scored on a two-out base hit to right by Kelly Johnson.

Alvarez was replaced by Evan Crawford after Munenori Kawasaki's leadoff single in the seventh. Figgins sacrifice Kawasaki to second but Crawford got Dustin Ackley and Ichiro Suzuki to ground out.

Casey Janssen worked the eighth and Francisco Cordero gave up Olivo's second homer of the season in the ninth.
