Andrus started an injury rehab assignment with Double-A Frisco on Monday night. He went 0-for-3 at the plate and had four assists on defense while playing five innings.
Andrus got hit on his throwing elbow by a fastball from hard-throwing reliever Keynan Middleton in the ninth inning of a 7-2 loss to the Los Angeles Angels on April 11.
This is the first time in his 10-season career that Andrus has been on the disabled list. Monday was the first day he was eligible to be reinstated from the 60-day DL, but he is expected to play several rehab games. He is scheduled to be the designated hitter when the RoughRiders play a mid-day game Tuesday.
