Rapid Reaction: Brewers 6, Cubs 4

MILWAUKEE -- A quick look at the Chicago Cubs' 6-4 loss to the Milwaukee Brewers on Saturday night at Miller Park.

How it happened: Ryan Dempster (15-4 lifetime against the Brewers) didn’t come calling with his best stuff on Saturday. The Brewers hit two homers, a triple and three doubles off the Cubs veteran starter in his four innings of work. Dempster left the game for pinch hitter Tony Campana in the top of the fifth. Dempster’s start was his worst since July 20, when he gave up six runs in three innings against the Philadelphia Phillies. Brewers starter Yovani Gallardo allowed just one run through seven innings on a second-inning RBI single by Alfonso Soriano. Soriano also drove in three more runs with an eighth-inning double off LaTroy Hawkins.

What it means: The Cubs have fallen back into a losing rut, dropping six of their last seven games after winning seven of their previous 10. They are now a season-worst 22.5 games out of first place in the NL Central.

Outside the box: Castro continues to lead the National League with 169 base hits. Going into play on Saturday night, the Cubs were tied with Cincinnati for the most home runs in August with 33. Aramis Ramirez (16) and Starlin Castro (11) extended their hitting streaks.

What’s next: Cubs right-hander Casey Coleman (2-6, 7.59) faces Brewers right-hander Zack Greinke (12-5, 4.22) on Sunday at 1:10 in the series finale.
