Scott Feldman felt good most of the night, but couldn't get out of a fifth-inning jam, as the Baltimore Orioles rallied for four runs.
Three of those runs came with two outs, as J.J. Hardy had an RBI double and Nate McLouth belted a two-run homer over the right field fence.
"I was close to getting out of it, but really couldn't get that final out and that is frustrating," Feldman said. "I felt I was so close to limiting damage there and that's all you're trying to do in that situation."
The Orioles had a 5-1 lead after that, and held on for a victory.
Feldman lost his third consecutive decision, and turned in his shortest start since July 4.
Here are a few other notes:
* The Rangers didn't get much going against Orioles starter Chris Tillman, who has a 1.93 ERA in two career starts at Rangers Ballpark. "He was locating well, getting ahead of guys," Michael Young said. "He had kind of a sneaky fastball. He pitched well."
* Ian Kinsler belted his 14th home run, a solo shot in the third inning. It was his first homer since Aug. 2.
* The Rangers' bullpen -- Michael Kirkman, Tanner Scheppers and Robbie Ross -- allowed one hit over four innings to extend its scoreless streak to 11 1/3 innings over the past five games.
