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 Cubs over the Brewers 12-11 in Chicago.

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.
