Sunday was a frustrating cap to a frustrating series for the Rangers. They were swept and fell a season-high three games behind the A’s in the AL West, plus 1.5 games back in the wild card chase. Here’s a roundup of our coverage from the day:

Rangers doomed by sloppy defense, poor hitting in another loss to Orioles
At various points in the game, the Rangers forced Martin Perez to get six outs in an inning, had a runner fail to score from second on a throw that wouldn’t have had a chance and allowed Chris Tillman to match his longest outing ever. In other words, rough night.
