The Rangers put Choo on the 15-day DL on Monday with a strained left hamstring.
Choo had been out since April 9 because of a strained right calf when he was activated before Friday's game at Houston. He walked twice in his only at-bats before leaving the game with the hamstring issue. He didn't play the rest of the series, so the DL move is retroactive to Saturday.
The team didn't immediately make a corresponding roster move.
Outfielder Drew Stubbs was also hurt. He was dealing with a sprained left little toe he suffered while running the bases Sunday.
