DETROIT — Chris Davis cleared the fences twice, giving him a major-league leading 26 homers, to help the Baltimore Orioles beat the Detroit Tigers 13-3 Wednesday.

Davis hit a two-run homer and Taylor Teagarden followed with a three-run home run in Baltimore's six-run fourth. Against embattled reliever Jose Valverde, Davis hit another two-run shot for his second multihomer game of the season and the fifth of his career.

The Orioles improved to a season-high 11 games over .500 after beating the AL Central-leading Tigers twice in the three-game series.

Chris Tillman (8-2) gave up three runs and seven hits over five-plus innings. He became the third pitcher in franchise history to win his first six decisions on the road, joining Jeff Ballard (1989) and Hoyt Wilhelm (1959).

Tillman gave up two singles and a walk in the first, but didn't give up a run because Austin Jackson was caught stealing second and Victor Martinez struck out to end the inning with Miguel Cabrera and Prince Fielder on base.

Rick Porcello (4-4) allowed six runs on nine hits, giving up a pair of homers for the third time this year.

Cabrera had two hits to become the first player to have at least 100 hits and 71 RBIs through his team's first 70 games since Boston's Ted Williams in 1948, according to STATS.

Porcello started off pitching three scoreless innings, giving up just two hits, before the Orioles scored six runs on seven hits in the fourth inning.

Davis hit the first pitch he saw to opposite field, clearing the wall in left, with Nick Markakis on to make it 2-0. Teagarden followed with a three-run homer. Nate McLouth's RBI double made it 6-0.

Omar Infante hit an RBI double in the fourth and pinch-hitter Matt Tuiasosopo — the first to face Baltimore reliever T.J. McFarland — hit a two-run double in the sixth to pull Detroit within three runs.

Baltimore restored its cushion the next inning, scoring three runs to take a 9-3 lead.

Valverde entered the game in a low-pressure, non-save situation down by six runs and failed miserably. He gave up three hits — including Adam Jones' two-run double — in five pitches and was booed by the fans who were still sticking around to see the end. Valverde kept his 10th pitch down, but Davis sent it deep into the right-field seats to put the Orioles ahead by 10 runs.

NOTES: Baltimore has been slightly better on the road (22-16) than at home (20-15) this year. ... Detroit dropped its second straight game in Comerica Park after winning 10 of 13 at home.
