The Rangers outhit the Orioles and scored four runs in the final five innings, but Baltimore's five-run fourth against Cliff Lee proved too much of an obstacle to overcome in an 8-6 loss.
Lee's shortest outing of the year lasted 5 2/3 innings. He allowed eight runs on 10 hits and walked a batter before giving way in the sixth inning to Scott Feldman, who could not start the seventh because of apparent discomfort in his left knee.
Orioles rookie third baseman Josh Bell did the most damage to Rangers pitching, bashing two home runs (both off Lee) and coming within a few feet of another. He finished 3-for-4 with five RBIs and three runs scored.
The Rangers were decent on offense but didn't push runs across until the fourth inning, down 2-0. Josh Hamilton was 3-for-5 with a homer, improving his batting average to .356. Michael Young also had three hits.
But Texas was also 3-for-11 with runners in scoring position, leaving seven stranded.
One bright spot for the Rangers was the debut of left-hander Michael Kirkman who retired all four batters he faced -- striking out the first three -- while filling in for Feldman.
