Diamondbacks' Christian Walker: Slugs three extra-base hits

Walker went 4-for-5 with a home run, two doubles, a run and four RBI in a 7-4 victory over Colorado on Sunday.

Walker opened the scoring with an RBI double in the first inning, connected on a 460-foot three run home run in the third, singled in the fifth and doubled again in the ninth for his first four-hit game of the season. The outburst comes on the heels of him reaching base four times Tuesday, and the 31-year-old is 10-for-21 with three walks across his last six games. The long ball was Walker's 27th and pulls him into a tie with Anthony Rizzo for eighth most in MLB.
