Cosart got knocked out in the second inning after giving up two homers to Kris Bryant, and the Marlins lost 7-2 to the Chicago Cubs on Saturday night. The Cubs' prized rookie came through with his second multihomer game, hitting a long two-run drive in the first and chasing Cosart (1-4) with a grand slam in the second. Three Marlins relievers combined to hold the Cubs hitless the rest of the way. Cubs starter Clayton Richard (1-0) sailed into the seventh inning in his first major league outing since 2013, pitching the Cubs to their fourth victory in five games. Maddon recalled throwing batting practice years ago to Bruce Hornsby, who is sitting in on piano and keyboards with the band, years ago when he was on the Los Angeles Angels' coaching staff. There was a scary moment in the seventh inning when a hard foul ball by Addison Russell hit Cubs third base coach Gary Jones in the elbow. Chicago's Kyle Hendricks (3-4, 4.15 ERA) and Miami's Mat Latos (3-5, 5.27) both look to win their second straight start as the Cubs and Marlins wrap up their weekend series Sunday.
