The Chicago Cubs took care of business in Pittsburgh to set up a huge series at Wrigley Field. They carry momentum into a three-game set against the Milwaukee Brewers after winning three of four games against the Pirates. It’s a chance to chip away at the Brewers’ National League Central lead, beginning with Monday night’s series opener in what should be an electric atmosphere. It was a week of change for the White Sox after firing executive vice president Ken Williams and general manager Rick Hahn on Tuesday.
