CHICAGO (AP) — Marco Estrada's struggles and a punchless offense doomed the Brewers.
Travis Wood pitched two-hit ball for seven innings and the Chicago Cubs got home runs from Welington Castillo and Mike Olt in a 4-2 victory over the Brewers on Sunday.
Estrada (3-2) went five innings, giving up four runs and seven hits: five doubles and two homers. In nine games this season, Estrada has served up 12 home runs, second most in the majors.
Estrada said he didn't have a feel for his pitches, especially his changeup, which he left up on Castillo's two-run shot in the second that gave the Cubs an early 2-0 lead.
The Cubs extended their lead to 3-0 in the third after Starlin Castro and Luis Valbuena hit back-to-back doubles with two outs.
Olt hit his team-leading ninth homer in the fourth to make it 4-0.
"I was terrible. Plain and simple, terrible," Estrada said. "I got to figure things out. My off-speed pitches haven't been there and that's what's letting me down. Plain and simple, it's just a bad pitched game. I didn't even give the guys a chance."
The Brewers looked ready to pounce on Wood in the first inning, when the left-hander's command was off. Milwaukee loaded the bases with three walks before Khris Davis swung at the first pitch and grounded out to end the threat.
Brewers manager Ron Roenicke didn't have a problem with Davis swinging away because Wood was clearly trying to get ahead after three walks and a mound visit from Cubs pitching coach Chris Bosio. Roenicke was more bothered by his team's inability to capitalize on an early scoring chance.
"The first inning or two, when you have a pitcher in trouble, you need to get to them early," Roenicke said. "That's what happened with us (Saturday). They get some people on base, they got some big hits in that first inning, they scored the runs and that's all they needed. So when you get those opportunities early, you need to do something. We didn't get the big hit there."
Wood (4-4) allowed two runs and struck out seven and the Cubs took two of three from the NL Central leaders to win a series for the second time this season.
