DENVER, Sept. 21 (UPI) -- Adam Dunn knocked in three runs Sunday to key Arizona's 13-4 rout of Colorado.
He started the rout with an RBI single when Arizona scored five times in the top of the first inning.
Fellow outfielder Chris Young drove in four runs with three hits.
Young hit a three-run triple and finished a double away from hitting for the cycle.
Five others, including winning pitcher Dan Haren, knocked in one run and one scored on Seth Smith's first inning error.
Conor Jackson had four hits and one RBI, and, like Young, Haren had three hits in the Diamondbacks' second straight victory.
Haren (16-8) yielded three earned runs and seven hits in six innings.
Colorado's Garrett Atkins belted a fourth inning three-run homer.
A run scored on Mark Reynolds' seventh inning error, while Smith and Chris Iannetta had two hits each for the Rockies, who have lost two in a row following a three-game winning streak.
The losing pitcher was starter Greg Reynolds (2-8).
