HOUSTON -- Alex Rios aggravated his sprained right ankle sliding into home plate in the top of the fourth inning on Sunday against the Astros. He was replaced in right field by Jim Adduci to start the bottom of the inning.
Rios will be re-evaluated on Monday at Arlington, when the Rangers start a seven-game homestand.
As soon as Rios stood up it was obvious something wasn't right physically. He walked toward the Rangers dugout gingerly.
Rios was making a start in right field after sitting out the first two games of the series at Minute Maid Park, in an attempt to give the ankle more time to heal. Rios sprained the ankle on July 19 at Toronto and missed three games from July 20-22 due to the injury.
