The Rays optioned Bigge to Triple-A Durham on Thursday, Marc Topkin of the Tampa Bay Times reports.
The 26-year-old righty will be squeezed out of the big-league bullpen as Richard Lovelady (forearm) returns from the injured list. Bigge has given up just one earned run in 7.1 MLB innings this season, and he has not been scored upon in four frames since joining the Rays.
