Texas Rangers general manager Jon Daniels said Alexi Ogando's groin strain will likely keep him out of the big leagues for four to six weeks.

"It was a little more significant than we expcteed to see," Daniels said about the strain.

The Rangers have not announced a starter for Saturday, though Michael Kirkman and Robbie Ross are probably candidates.

Roy Oswalt will start on Tuesday for Double-A Frisco, and Daniels said nothing has changed on the Oswalt front.

"He is starting tonight. We'll evaluate after that," Daniels said. "Nothing has changed. It’s going to be predicated on how he’s feeling, how he’s doing and what our needs are. We want to be sure he’s 100 percent ready to come up both on his arm and conditioning."

Daniels did feel like there was good news on the Neftali Feliz and Derek Holland injury fronts. Feliz was examined again by doctors and is doing better. It sounds like the sprained ligament may have been an older injury that showed up on the MRI. He will see Dr. Keith Meister again this weekend, since that will mark four weeks since he stopped throwing, and could begin a throwing program shortly thereafter.

Holland has put some weight back on and is working out. He should be ready to throw soon as well.

At this point, Daniels said going outside the organization for pitching help isn't a top priority.

"We’re always going to consider all of our options and I think we’re probably still a month away from the trade market really heating up or at least a few weeks, but that’s not where our mindset is," Daniels said. "We’ve gotten fairly good news on Derek and Neftali. Roy is making progress and will get stretched out. Alexi will be back. It's not a long-term injury. Our mindset is to weather the storm and get our guys back and reassess at that point."
