"When I get guys out, I have my good two-seam fastball working and my curveball working," Estes said. "Today, I had both and the guys played good defense behind me."
Five days ago, Chacon gave up just three hits in seven innings as the Rockies beat Estes and the Cubs, 8-5, at Coors Field.
The rematch appeared to favor Chacon, who entered Friday's start with a National League-best 1.04 ERA. Estes, bothered by a bad back at Colorado, was coming off a pair of rough outings and came in with a 7.43 ERA.
But Estes (2-3) better handled the blustery conditions at Wrigley Field, walking two and striking out two on a day when a number of fly balls were affected by a 20 miles-per-hour wind blowing in from left field. He also benefited from four double plays and helped his cause with an RBI single.
"The last time pitched here, I came to the park and they (winds) were blowing straight out," Estes said. "Today, it was nice to see them blowing straight in, but my game plan stayed the same."

"Last week, he was a different pitcher than we had seen," Cubs manager

Chacon's ERA climbed more than a run to 2.27. He had alllowed only four earned runs in his previous five starts covering 35 2/3 innings.
"I didn't have my fastball command today and that's what hurt me, and that's what has been the key to my whole season," said Chacon, who was named National League Pitcher of the Month earlier in the day. "And when I don't have it, this is what happens."

"This year has been frustrating for me," said Bellhorn, who went 2-for-2 with a walk to snap out of a 2-for-18 slump. "I've tried too hard. But today I just tried to have fun. The three, four days Dusty gave me off relaxed me and reminded me why I'm here."
