Seattle, WA (My Sportsbook) - The Minnesota Twins strengthened their bullpen Monday, acquiring pitcher Eddie Guardado from the Texas Rangers in exchange for minor league pitcher Mark Hamburger.

The 37-year-old Guardado appeared in 55 games for the Rangers, going 3-3 with four saves and a 3.65 earned run average. This will be Guardado's second tour of duty with Minnesota. Originally drafted by the Twins in 1990, the left-hander spent 13 years in the organization from 1991-2003.

Guardado was named to two All-Star teams and recorded a pair of 40-save seasons during his initial tenure with the Twins when he earned the nickname "Everyday Eddie."

For his career, he is 44-58 with 187 saves and a 4.27 ERA in 851 games (25 starts) for the Twins, Mariners, Reds and Rangers.

To create room on the roster for Guardado, the club designated infielder Mike Lamb for assignment.

Lamb batted .233 with one home run and 32 RBI in 81 games for the Twins this season.

Hamburger, 21, was 1-2 with 13 saves and a 4.17 ERA in 27 appearances with Elizabethton of the Appalachian League.

In a related move, Texas also purchased the contract of pitcher Bill White from Triple-A Oklahoma to take Guardado's spot on the roster.
