LHP John Gaub was claimed off waivers by the Rangers.
The Rays had claimed Gaub off waivers from the Cubs on April 5, and the 27-year-old was working middle relief for Triple-A Durham, going 0-1, 4.32 with one save in 16 2/3 innings over 16 games.
The Rays took him off the 40-man roster Monday to make room for the addition of INF Drew Sutton, who was acquired from Pittsburgh's Triple-A team to fill the void created by Jeff Keppinger's injury. Gaub had four big-league appearances with the Cubs in 2011.
The Rangers optioned Gaub to Triple-A Round Rock.
