Trammell is out of the lineup for Sunday's game against the Diamondbacks.
Nelson Velazquez will enter the starting nine in place of the left-handed-hitting Trammell, who will hit the bench while southpaw Eduardo Rodriguez takes the hill for Arizona. Trammell had been included in the lineup in each of Houston's last five games, going 4-for-15 with three doubles, two walks, one stolen base and one run.
