Walker went 2-for-3 with a walk and a solo home run in Friday's 8-6 win over Pittsburgh.
Walker cranked his team-leading 14th homer, his eighth in the last 17 games, in the second inning to even the score at 1-1. The first baseman's .190 BABIP has led to a .211 batting average, but Walker leads the team in slugging (.489), with 22 of his 38 hits going for extra bases. He also leads the Diamondbacks with 26 RBI.
