HOUSTON — A decision has yet to be made whether to put left-hander Martin Perez on the disabled list.The Texas Rangers are going to make that call Wednesday when they must clear a spot and recall right-hander Nick Tepesch from Triple A Round Rock to make that day’s start.Perez told the club he felt discomfort in his left elbow after his start Saturday against the Red Sox and underwent an MRI exam that revealed some inflammation.Manager Ron Washington said it was possible that Perez could avoid the DL and miss only one start.“Our thought is to wait and see what more information we have,” Washington said. “If it’s just for him to miss a start, then we have to do something else [to clear a spot for Tepesch].”Perez started the season well and had thrown back-to-back complete-game shutouts before going 0-3 with a 12.83 ERA in his following three starts, including Saturday.Perez said Sunday he believed he’d be ready to go after missing only one start.Rotation decisionsRobbie Ross has struggled in each of his past three starts and is scheduled to get a couple extra days off the next time through the rotation.Ross, transitioning from reliever to starter, isn’t scheduled to pitch again until next Tuesday against Seattle, which would give him eight days of rest.Washington said the Rangers will go with Yu Darvish, Colby Lewis and Matt Harrison in the three-game series against Toronto this weekend, with the thought it would keep Lewis and Harrison from pitching — and batting — when the team faces the Nationals in Washington at the end of the month.Pushing Ross back also gives the Rangers another option for that rotation spot. Veteran lefty Joe Saunders, on the DL with a stress fracture in his left ankle, is scheduled to throw a rehab start for Round Rock on Thursday and would be in line to start again Tuesday.More Moreland?Mitch Moreland went into Monday’s game with a .500 batting average (8 for 16) in May with four RBIs.He was batting .301 for the season in a part-time role, but Washington is trying to find more ways to get him on the field. That’s why he started Moreland in left field Monday, only the fourth start in the field for Moreland this year.Washington said he would like to get Moreland consecutive days in the field, but it seems unlikely this series with the Astros starting a left-hander Tuesday.Moreland hopes his results lead to more playing time, but isn’t overly concerned about it.“Everyone wants to be in there every day,” Moreland said. “But I try to go out there and be ready when I get my chance and opportunity and make the most of it.”Briefly• The Astros are the only AL team Matt Harrison has not beaten. Harrison would like to do that Tuesday, of course, but has another goal in mind: “I’d definitely like to go out and pitch deeper in the game. I’ve got to limit those walks and get ahead of guys more often.”• The Rangers are expected to face the AL’s ERA leader, Mark Buehrle, on Saturday, and the 2012 NL Cy Young award winner, R.A. Dickey, on Sunday with the Blue Jays in town.• Infielder Josh Wilson, the Rangers’ Opening Day second baseman, accepted his assignment to Triple A Round Rock. The Rangers designated Wilson for assignment Thursday.
