Carlos Villanueva won his fourth straight start, Travis Snider hit a two-run home run and the Toronto Blue Jays beat the Detroit Tigers 8-3 on Friday night.
Jeff Mathis drove in three runs with a bases-loaded double and Omar Vizquel had two hits as Toronto won for the fifth time in seven games.
Miguel Cabrera and Prince Fielder hit back-to-back homers for Detroit in the first inning but the Tigers lost for the third time in four games.
Cabrera's homer was his 25th, and raised his major league-leading RBI total to 83. For Fielder, the homer was his 16th.
Detroit has won nine of 14 since the All-Star break but is just 3-4 away from home in that time.
Rick Porcello (7-6) failed to extend his road winning streak to four games, allowing five runs and six hits in six innings. Porcello, who won a career-best four straight road games as a rookie in 2009, walked two and struck out one in his first road defeat since June 8 at Cincinnati.
Villanueva (6-0) saw both Cabrera and Fielder go deep over a three-pitch span in the first inning, but didn't give up another run. Unbeaten in five starts since joining Toronto's rotation after 22 relief appearances, the right-hander allowed four hits in five innings, walked two and struck out three.
Aaron Loup worked 1 1-3 innings, Brandon Lyon got two outs, Darren Oliver gave up Fielder's RBI single in the eighth and Casey Janssen finished.
Toronto cut Detroit's early lead in half with a run in the bottom of the first. Omar Vizquel doubled, his first extra-base hit of the season, and scored on Edwin Encarnacion's two-out single.
The Blue Jays took the lead with a four-run fourth, loading the bases with a single and two walks before Mathis hit a two-out double just beyond the reach of Quintin Berry in left, clearing the bases. Anthony Gose followed with a bad-hop single that eluded Fielder, giving the rookie outfielder his first career RBI.
After Yan Gomes reached on a throwing error by second baseman Omar Infante in the eighth, Snider followed with a blast to right-center, his third in five games.
