The Rangers announced last week that they were ending their relationship with the Oklahoma City RedHawks after 28 years. The Rangers chose Triple-A Round Rock (Texas) as its new affiliate.
That left Houston without a Triple-A club and the RedHawks without a major-league affiliate. They announced their affiliation Monday.
The Astros were the original big-league affiliate of Oklahoma City's minor-league franchise from 1962 to 1972.
