DETROIT -- Chris Davis hit a pair of two-run homers, giving him a major-league high 26 home runs, and drove in five runs to power the Baltimore Orioles to a 13-3 win over the Detroit Tigers on Wednesday at Comerica Park.
Davis collected his fifth career multi-homer game and second this season. Taylor Teagarden blasted a three-run homer, Adam Jones drove in three runs and Nate McLouth had three hits and scored twice for Baltimore, which won the season series, 4-2.
Chris Tillman (8-2) survived five-plus shaky innings to lift his road record to 6-0. Tillman, who was charged with all three Tigers runs, gave up seven hits and walked three. He has allowed three or fewer runs in 12 consecutive road starts, the longest active streak in the majors.
Matt Tuiasosopo had a two-run double for the American League Central-leading Tigers, who surrendered a season high in runs.
The Orioles had seven hits and sent 10 men to the plate during the fourth inning against Rick Porcello (4-4) to take a 6-0 lead.
Nick Markakis led off with a single and one out later, Davis smashed a first-pitch offering from Porcello over the left-field wall. Singles by J.J. Hardy and Ryan Flaherty, sandwiching a strikeout, preceded Teagarden's blast to left field.
Teagarden had just one hit in 24 at-bats this season before the home run. Manny Machado's RBI single completed the Baltimore outburst.
Detroit cut the Orioles' lead to 6-3 on Omar Infante's RBI double in the fourth and Tuiasosopo's pinch-double in the sixth.
Davis contributed a run-scoring double during Baltimore's three-run seventh against relievers Darin Downs and Evan Reed. McLouth and Machado sparked the rally with a double steal. Jones' infield single and Hardy's sacrifice fly brought in the other runs.
Davis smacked his second homer, off Jose Valverde, during a four-run ninth.
