Fister (11-3) allowed one unearned run and six hits in 7 1-3 innings. He struck out seven and reduced his ERA to 2.49.

Gonzalez, Rockies destroy Cubs
DENVER -- Carlos Gonzalez homered, doubled and singled in his return to the lineup, and the Colorado Rockies snapped a five-game losing streak with a 13-4 victory over the Chicago Cubs on Wednesday night.
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 (6-3). 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 (6-1) came off the 60-day disabled list to earn his first win since May 10 (see full recap).
