Mired in their first rough stretch of the season and facing the hottest team in baseball, the Chicago Cubs still have good reason to feel confident knowing Jake Arrieta is set to take the mound. Looking to extend a franchise record by winning their 22nd consecutive regular-season game started by Arrieta, the visiting Cubs try to keep the San Francisco Giants from a ninth straight victory Friday night. "You're not going to win them all, despite feeling like you can," manager Joe Maddon said after the Cubs dropped two of three at Milwaukee with Thursday's 5-3 defeat.
