Yovani Gallardo clutched his leg and hobbled off the field, the latest blow in a brutal season for the Milwaukee Brewers. An injury to one of their top trade chips with the non-waiver deadline approaching was the big news on a day when they built an early lead and then came back to beat the Cubs. Jean Segura hit a solo homer and the go-ahead double, Khris Davis added a three-run shot, and the Brewers rallied for a 6-5 victory over Chicago after Gallardo left with a hamstring problem in the first game of a day-night doubleheader Tuesday.
