Walker went 1-for-4 with a double and an RBI in Monday's 6-3 loss to the Giants.
Walker was back in the lineup after getting a day off Sunday. Arizona manager Torey Lovullo talked to Alex Weiner of Arizona Sports on Monday about giving Walker time off following his return from an oblique injury. "Yesterday I took [Christian] Walker out of the lineup... It's probably about three or four days too late to give him a day off, talking to the medical team," Lovullo said. Walker should be available for the final five games of the season.
