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.

Though he'll be on the bench while the White Sox send southpaw Anthony Kay to the hill for the series opener, the left-handed-hitting Trammell appears to have usurped LaMonte Wade in the strong side of a platoon in the corner outfield. Trammell cracked the lineup for each of the Astros' last five matchups with right-handed starters, but he went just 1-for-15 with a 1:2 BB:K during that stretch.
