The Rays aren't sure when third baseman Evan Longoria will be healthy enough to return to the field. Longoria has been sidelined since May 1 with a partially torn left hamstring. "I have no idea when he's going to be able to play again," manager Joe Maddon said. "It's such a hard one to create conjecture with. If you wanted to bend to the negative side on this one you may have to as opposed to the positive side of it, meaning it will probably take more as opposed to less time to get him back on the field." Longoria was shut down after he felt discomfort in the hamstring during a minor league rehab assignment last month.
