Calhoun is not in the lineup for Saturday's tilt with Boston, Jeff Fletcher of the Orange County Register reports.
He'll be replaced in the lineup by Shane Robinson, who's starting in right field and batting ninth. Calhoun's production has dipped slightly since the start of the second half, as he's gone just 10-for-47 (.213) in his last 14 games. He does have eight runs and seven RBI during that span, however.
