"It's about consistency at the Major League level," Daniels said. "Those guys have had outings where they've shown everything we love about them, but their last few outings have been below a level in which we can count on. Until we see consistency, it's hard to count on that."Daniels said it's also unlikely that they will call up Barret Loux or Justin Grimm from Double-A Frisco. Both have pitched well so far this season. "I would expect [Feldman] to continue to start, but we haven't sat down and talked about it," Daniels said. Oswalt is an 11-year veteran who won 20 games for the Astros in both 2004 and 2005. He was 9-10 with a 3.69 ERA in 23 games for the Phillies last season but has yet to sign with anybody. The Rangers had some interest in him during the offseason but declined to pursue it seriously. Oswalt, who lives in Mississippi, has expressed a desire to pitch for the Rangers or the Cardinals, but is also being looked at by the Tigers, Red Sox and other clubs. "We're going to consider all our options and what's best for the club going forward, whether it's internal options or external," Daniels said. Feliz first experienced some soreness in a start against the Angels on May 13. He thought it was normal soreness and didn't say anything. But the soreness was still there after Friday's start against the Astros. He brought it to the club's attention, and the Rangers sent him to Arlington on Monday to have an MRI. The examination showed a sprain in the ulnar collateral ligament but no tear. He will not throw for at least four weeks. Once he gets clearance, Feliz will begin a throwing program but will likely need several weeks to rebuild his arm strength. "Obviously he's going to be down for a little while," Daniels said. "We're going to review our options and see where we are going to go from here." Feliz spent the past two years as the Rangers' closer before being switched to the rotation this season. Daniels said the Rangers have to consider the possibility that moving into the rotation contributed to the problem. "That's something we have to talk about," Daniels said. "We don't know the answer. He is as strong and as well-conditioned as he's ever been. There weren't any warning signs. But everything is on the table for discussion."
