Out since July 5 with a bruised left heel, Danby Swanson said he was getting “stir crazy.” After a game that was simply crazy, the Chicago Cubs celebrated Swanson’s return Saturday with a big win against the rival St. Louis Cardinals. Swanson had two of the team’s 15 hits and Cody Bellinger stayed hot with four RBIs as the Cubs rallied from three deficits and, after two rain delays, emerged with an 8-6 victory in front of 40,425 fans at Wrigley Field. “The game can be played so many different ways,” Swanson said.
