Stewart is hitting .291 with 12 home runs, five doubles, a triple and 38 strikeouts in 117 at-bats. The Rockies have asked Stewart, who went 3-for-47 with 18 strikeouts in the Majors, to adjust his hand positioning and stance.
"I get daily updates; I just talked to him on the phone the other day," Tracy said. "He's obviously doing some damage at the Triple-A level right now. When we get to the point where everyone is comfortable with the fact we've done everything we possibly can and given him every opportunity to re-instill all the confidence in himself we want him to have, we'll move forward."
One reason the Rockies can afford to make sure Stewart, who had problems with pitches middle-in, is ready is the performance of Ty Wigginton at third base. Wigginton is hitting .300 with seven doubles, five home runs and 13 RBIs since May 23.
