The Rays optioned Bigge to Triple-A Durham on Saturday.
The 27-year-old will end up as the roster casualty necessary to make room in the bullpen for Cole Sulser (back), who returned from the injured list Saturday. Bigge owns a 6.98 ERA and 1.45 WHIP through 19.1 innings with the Rays this season and gave up three earned runs without recording an out during his last appearance Friday.
