Gonzalez homers as Rockies rout Cubs, 13-4.
Corey Dickerson had four hits, drove in three and was a homer shy of the cycle. Mike McKenry also homered for Colorado.
The Rockies hadn't won since beating the Cubs last week at Wrigley Field, but ended their struggles with a big sixth inning against starter Jake Arrieta. Trailing 4-3, the first seven batters had hits, including Gonzalez's 11th homer, a two-run shot that gave the Rockies a 6-4 lead.
Gonzalez had not started since aggravating his sprained right ankle in Detroit on Friday.
Jordan Lyles came off the 60-day disabled list to earn his first win since May 10.
