Diamondbacks' Christian Walker: Homers in win

Walker went 1-for-5 with a solo home run in Friday's 7-3 win over the Rockies.

Walker hit the second of back-to-back home runs on the first inning after Lourdes Gurriel went deep before him. It was the first homer for Walker, who has a hit in both games to start the season. He's locked in as Arizona's primary first baseman and cleanup batter.
