ARLINGTON (May 24, 2012) -- The Texas Rangers have acquired left-hander John Gaub on a waiver claim from Tampa Bay.
Gaub was added to the Rangers' 40-man roster Thursday and optioned to Triple-A Round Rock.
Texas didn't have to make any corresponding move because it had an open spot on the 40-man roster.
In 16 relief appearances this season at Triple-A Durham, Gaub was 0-1 with a save and a 4.32 ERA. The Rays had acquired Gaub off waivers from the Chicago Cubs on April 5.
In his only major league stint, Gaub had a 6.75 ERA over four relief appearances for the Cubs in the final month last season.
