The Rangers said Tuesday they have agreed to a minor league contract with an invitation to spring training for the oft-injured 2010 AL MVP.
Hamilton, 35, had his best years in Texas as a five-time All-Star, including trips to the World Series in 2010 and '11.
Hamilton was released in August, closing the books on a $125 million, five-year deal signed with the Los Angeles Angels in free agency after the 2012 season.
The Angels traded Hamilton back to Texas after two injury-plagued years. The outfielder played just 50 games in two more seasons with the Rangers, missing all of last year with a left knee injury that required surgery.
The Rangers also signed right-hander Dillon Gee to a minor league deal. He pitched for Kansas City last season and had thoracic outlet surgery in October.
