Last year, on their way to a franchise-record 106 losses, Milwaukee took 10 of 17 meetings with Chicago, including four of seven at Wrigley Field. Five of those victories came during the Cubs' nine-game losing streak in May.
The Brewers had a winning record against just one other team last season.
Asked to explain Milwaukee's success against Chicago, Sheets said, "It was the luck of the draw. I don't know. But the atmosphere here is different, so maybe we are more focused."
"Any win is big," Brewers manager
added. "It doesn't matter who we are playing. But it's the Cubs, so it's huge. We're two hours away, so it's a big rivalry. But we haven't gotten a lot of wins, so any win is huge."
Sexson sent starter
's 2-2 pitch over the left-center field wall with two outs to cap a three-run third inning. Sexson, who hit six homers off Cubs' pitching last season, moved into a tie with Houston's
for the major league lead with 11.
"I do enjoy playing here," said Sexson, who has a .344 average at Wrigley Field. "It's one of the last old great ballparks still standing. It's got such great history. Guys like coming here to play."
In the sixth, Helms belted Clement's (2-4) first pitch into the right-center field bleachers to make it 5-1. It was his fifth home run of the season and fourth in seven games.
Staked to a four-run lead, Sheets (3-3) improved to 6-0 lifetime against Chicago. He allowed three runs and five hits in 7 2/3 innings with a walk and five strikeouts.
"He did a great job," Sexson said. "He worked both sides of the plate, kept them off-balance, and he didn't fall into a pattern."
Sheets served up a home run to rookie
Hee Seop Choi
with one out in the second but retired 19 of the next 21 batters before
homered with two outs in the eighth.
"He's a heck of a pitcher," Cubs manager
said of Sheets. "I haven't been here to see him before. We hit some balls hard off him, but he threw the ball well."
