The Monday night tweak and ensuing soreness third baseman Evan Longoria felt in his left hamstring Tuesday was obviously not good. But he and the Rays say they won't know for a couple of days just how bad of a setback he sustained.

Longoria said, "I really don't view it as a huge setback" and tried to frame it as a positive development in that he heeded the warning and didn't re-injure himself more severely. "That's my hope now, that it was just a little tweak and that the pain will subside in the next couple days and we'll be able to continue to move forward like we were," he said.

But Longoria, who pulled himself out of Monday's rehab game with Triple-A Durham, acknowledged he didn't know how much longer his return from the April 30 partial tear would be delayed: "I hate to put a time on it."
