07:18 AM ET 08.08 | While some had speculated that his career may be over, Lance Berkman remains planted on the comeback trail. [Berkman] continues to make progress on his way back from left hip inflammation, but the Rangers' designated hitter said on Wednesday that he doesn't have a clear idea of when he will go on a rehab assignment. ... The Rangers have used the DH spot to rotate everyday players through it for a rest day, but they will gladly take back Berkman's veteran presence as regularly as his hip and achy right knee allow it. But they aren't rushing Berkman back in the wake of the 50-game suspension Nelson Cruz started serving Monday. "That's going to be based on what he can withstand," manager Ron Washington said. "If his bat can be as active as it was the first month of the season, darn right he's going to play."
