Walker went 1-for-5 with a solo home run in Wednesday's win over the Royals.
Walker launched a solo shot off Michael Wacha in the top of the fourth, going back-to-back with Joc Pederson to give Arizona a 3-1 lead. It was the first baseman's 23rd long ball of the campaign and his first since July 4 against the Dodgers. Walker has also driven in at least one run in the last two games, bringing his RBI total up to 17 in the month of July.
