"It's been 12 or 13 days now, so we're just trying to get further from it," D-backs manager Kirk Gibson said. "He's good to pinch-hit."
Gibson added that Chavez could start, but that the club doesn't want to risk needing to remove him early in a game if the hip stiffened again.
Chavez missed most of June with a right oblique strain and is batting .226 in 31 at-bats since returning from the disabled list June 29. Gibson said the club is still mindful of the oblique injury.
"If [an oblique] scars, it's not flexible," Gibson said. "We don't want him to be out for a while."
