MILWAUKEE -- Christian Yelich used his legs. Lorenzo Cain used his head.
And the Brewers used the Cubs' big mistake to double their lead to 4-0 in the latest installment of an entertaining series between the National League's top two teams.
Travis Shaw delivered his second two-run double in as many at-bats Tuesday at Miller Park after the Cubs botched a third-inning rundown with Yelich and Cain on the basepaths. Yelich was at second base after a walk and an errant pickoff throw by Cubs pitcher Tyler Chatwood, whose troubles were just beginning.
