Rockies optioned OF Sterlin Thompson to Triple-A Albuquerque.
Thompson retreats to the minors with Mickey Moniak returning from the injured list. The 24-year-old rookie has hit .232 (16-for-69) with two homers and 10 RBI in 27 games for the Rockies this season. He projects as more of a reserve outfielder than an everyday option at the highest level.
