The Rangers have claimed 25-year-old outfielder Joe Benson off of waivers from the Twins, tweets MLB.com's Rhett Bollinger. Apart from a brief call-up in 2011, Benson has spent his entire career in the minors.
Thus far, he has struggled to a .192/.256/.285 line in 164 plate appearances for the Twins' Triple-A affiliate. The claim enabled the Twins to free a 40-man roster spot for pitcher P.J. Walters to take the rotation spot of the scuffling Vance Worley.
The Rangers subsequently optioned Benson to Double-A, according to Evan Grant of the Dallas Morning News (on Twitter). To make space on the team's 40-man roster, Texas moved Matt Harrison to the 60-day DL, according to a tweet from Jeff Wilson of the Fort Worth Star-Telegram.
