The Chicago Cubs’ hitters aren’t putting enough balls in play, and their pitchers aren’t keeping balls in play. That combination has the Cubs heading back to Chicago on the brink of elimination. Chicago gave up three homers and mustered just one hit after the second inning of a 7-3 loss at Milwaukee on Monday night that gave the Brewers a 2-0 lead in their best-of-five NL Division Series. The Cubs must win two straight in Chicago on Wednesday and Thursday to send the series back to Milwaukee for a deciding Game 5 on Saturday.
