Brandon Phillips hit a grand slam and matched his career high with six RBIs, and the Cincinnati Reds extended their dominance over the Chicago Cubs with a 6-2 win Monday night in foggy conditions at Wrigley Field. Phillips had an RBI single in the first, connected off Scott Feldman (5-5) in the third and an RBI groundout in the sixth for his fourth-career game of six RBIs. Across town, the Chicago White Sox and Toronto Blue Jays were delayed over an hour because of a dense fog but the Cubs and Reds were never halted. The Reds were coming off a weekend series loss to NL Central-leading St. Louis and had lost four of five overall. Homer Bailey (4-4) picked up his first win since beating the Cubs on May 25.
