The Chicago Cubs took care of business against the Milwaukee Brewers before keeping the clubhouse doors closed until they were done watching the Pittsburgh Pirates lose.

Home field for the NL wild card game between Chicago and Pittsburgh will be decided on the final day of the regular season.

Kyle Hendricks allowed one hit and struck out eight in six innings, and the Cubs won their seventh straight with a 1-0 victory over Milwaukee on Saturday night.

The win, coupled with Pittsburgh's 3-1 loss at home to Cincinnati, pulled Chicago within a game of Pittsburgh in the wild card standings.

"We waited to celebrate our game until after that game was concluded. It's pretty interesting, isn't it? I'm really proud of our guys," Cubs manager Joe Maddon said.

Pittsburgh still needs a win Sunday or a Cubs loss to host the one-game playoff Wednesday night. If the Cubs beat Milwaukee — and the Pirates lose to Cincinnati again — the wild-card showdown would be played at Wrigley Field.

"It'd be huge," Hendricks said about the possibility of playing at Wrigley. "We feel confident in our team no matter where we play, but obviously the home atmosphere has been unbelievable ... and would help use out that much more."

Hendricks (8-7) held Milwaukee without a baserunner until Martin Maldonado singled with one out in the sixth. Maldonado grounded into a double play two innings later that allowed reliever Fernando Rodney to escape a first-and-third jam with one out.

Hector Rondon tossed a hitless ninth for his 30th save.

Addison Russell drove in the game's only run off Tyler Wagner (0-2), singling home Chris Coughlan from third in the second inning. The bevy of visiting Chicago fans cheered, making Miller Park feel like Wrigley North for another night.

The Cubs won despite leaving 12 runners on base.

But Hendricks proved to be a difference-maker. Counting Saturday's start, he will enter the postseason having thrown 12 straight shutout innings.

"I think tonight he had really good movement on the fastball," Brewers manager Craig Counsell said. "I don't think we had many pitches to hit the way I saw it."
