Belisario (shoulder) was assigned to Triple-A Durham on Wednesday, Marc Topkin of the Tampa Bay Times reports. Belisario had been in extended spring training as he rehabbed a fractured shoulder suffered in February, and appears to be about a week away from returning to game action. The 32-year-old wasn't expected to join the big league team upon his return, but he could earn the call up to the Rays' bullpen if he can prove he's healthy after spending some time in Triple-A.
