If this series was a playoff preview, the Orioles can’t wait. For the second time in the last three weeks, the Orioles beat one of baseball’s best, the Detroit Tigers in a series. The Orioles’ 13-3 win over the Tigers before 38,574 at Comerica Park on Wednesday, gave them four wins in six games against Detroit this season. It was the first time they’ve won a season series over the Tigers since 2008 and the most runs they’ve scored since Aug. 10, 2010. Baltimore (42-31) is now 11 games over .500 for the first time this series, and has now won six of its last seven series. Most impressive is the seven wins in the last 10 games against Los Angeles, Boston and Detroit. The Orioles equaled their season highs with a six run inning on seven hits in the fourth when they took a 6-0 lead over the Tigers (39-31). After Detroit scored three runs to make it 6-3 after six, the Orioles answered with three more in the seventh to put the game out of reach. Chris Davis hit an opposite field home run to left, a two-run shot, his major league leading 25th of the season off Rick Porcello (5-3). Taylor Teagarden, who missed more than five weeks after a dislocated left thumb, added a three-run shot. It was just Teagarden’s second hit of the season, and his first home run. The sixth run scored on a single by Manny Machado. Chris Tillman (8-2) won his fifth straight decision. He’s 6-0 on the road. Tillman wasn’t at his best, leaving after the first two batters reached in the sixth. He gave up three runs on seven hits in five-plus, walking three and striking out three.
