Corporan signed a minor league contract with the Marlins on Wednesday, Chris Cotillo of SB Nation reports.
Corporan was released by the Rays on Friday, but it didn't take long for another club to seek out his services behind the plate. The 32-year-old was a bit lackluster at the plate with the Rays' Triple-A affiliate, batting just .200 with two home runs and nine RBI in 65 at-bats, so he'll likely just act as organizational depth going forward if he can't improve his dreary numbers at the plate.
