CHICAGO -

Jonathan Lucroy hit a grand slam and drove in seven runs for Milwaukee, but Alfonso Soriano's RBI single capped a three-run comeback in the ninth inning Thursday that lifted the Chicago Cubs over the Brewers 12-11.

 In a seesaw game featuring a combined 15 extra-base hits, the Cubs led 3-0, trailed 9-3 and were still down 11-9 going into the ninth.

 Starlin Castro hit an RBI single against Francisco Rodriguez (2-7), Anthony Rizzo tied it with his second double of the afternoon and Soriano won the game with his one-out drive off the center-field wall.

   Lucroy tied his career high for RBIs and Rickie Weeks had five hits. Ryan Braun and Cody Ransom also homered for Milwaukee, which had won eight straight against the Cubs.
