Rangers add Benson; Harrison to 60-day DL

The Texas Rangers acquired outfielder Joe Benson on a waiver claim from the Minnesota Twins on Saturday and optioned him to Double-A Frisco.

To make room for Benson on the 40-man roster, the Rangers transferred injured left-handed pitcher Matt Harrison from the 15- to the 60-day disabled list.

Benson, 25, has struggled this season for Triple-A Rochester, batting .192 with a home run and nine RBIs in 42 games. He was a second-round pick of the Twins in the 2006 June draft.

Benson has played in 21 games in the majors with a .239 batting average, six doubles and a triple. He was rated as one of Baseball America's Top 100 prospects prior to the 2011 and 2012 seasons.

Harrison, who had two surgeries in April for an inflamed nerve in his lower back, isn't eligible to return to the Rangers until June 6.
