The Minnesota Twins have acquired their former closer, Eddie Guardado, from the Texas Rangers to bolster the bullpen.

In return, the Rangers get 21-year-old right-hander Mark Hamburger.

The 37-year-old Guardado was 3-3 with a 3.65 earned run average in 49 1/3 innings for the Rangers, who recently made him their closer after an injury to C.J. Wilson. Opponents are batting .220 against the left-hander this season.

Guardado has 187 career saves, 116 with Minnesota, where he played from 1993-03.
