An MRI on Thursday revealed no tear in Devil Rays CF Rocco Baldelli's injured left hamstring, but he still is expected to be sidelined for perhaps another month after re-injuring himself Monday during a rehabilitation game for Triple-A Durham. Baldelli, who has been out since May 16, felt a "tweak" during his fifth and final plate appearance in the second of four scheduled rehab games with the Bulls. Prior to that, he had been tentatively scheduled to rejoin the Rays' lineup as soon as today. Instead, the Rays now will allow him plenty of time to heal in order to salvage something from the season.
