(AP) -- Darwin Barney scored on a fielder's choice in the eighth inning for the game's lone run as the Cubs topped the Brewers 1-0 on Monday night.

Aramis Ramirez grounded to Brewers shortstop Yuniesky Betancourt with one out, but the throw to catcher Jonathan Lucroy wasn't in time to tag Barney, who dived over home plate for the score.

Cubs reliever Jeff Samardzija (4-2) worked one inning for the win, while Carlos Marmol picked up a save in the opener of a four-game series.

Brewers reliever Kameron Loe (2-6) also pitched one inning and took the loss.

Cubs starter Ryan Dempster had a no-decision in his 500th career game.

 He worked seven scoreless innings, gave up four hits while striking out seven and walking just one.
