ST. PETERSBURG, Fla. (AP) Wei-Yin Chen pitched seven effective innings, Adam Jones drove in two runs and the Baltimore Orioles beat the Tampa Bay Rays 2-1 on Saturday night.
Baltimore started the day 4 1-2 games behind Houston for the second AL wild-card spot.
Chen (10-7) allowed one run, six hits and struck out seven. He ended his outing by escaping a two-on, no-out jam.
Darren O'Day worked a scoreless eighth before Zach Britton got three outs for his 34th save.
Tampa Bay rookie Mikie Mahtook didn't start a day after tying a team record with five hits in a game. Manager Kevin Cash said a number of factors, including third baseman Evan Longoria being the designated hitter, led to his lineup decision.
Mahtook entered as a pinch-runner in the eighth after Grady Sizemore was hit by a pitch near his knee. Mahtook stole second, but the play was voided when Longoria was called for interfering with catcher Matt Wieters.
Mahtook then tried to steal again second with Logan Forsythe batting and was thrown out.
Erasmo Ramirez (10-6) gave up two runs and nine hits over seven innings. The right-hander was coming off a start against the Yankees in which he lost a no-hit bid in the eighth.
Chris Davis had a leadoff double in the sixth for his third hit and scored on Jones' single to put Baltimore up 2-1.
After Jones had an RBI grounder in the first, the Rays tied it in the bottom half on Richie Shaffer's double.
