Calhoun did not play in Monday's 11-4 loss to Atlanta.
Calhoun was activated from the injured list last Friday and served as the designated hitter in all three games over the weekend in Houston, but he was held out of the starting lineup once Arizona was back in an National League city. Calhoun's usual position, right field, was occupied by Henry Ramos. The Diamondbacks are evaluating or giving opportunities to several players younger than Calhoun. It doesn't mean he won't play again this season, but the veteran may no longer be a regular presence on the diamond.
