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.
Ransom led off the seventh with a go-ahead solo shot to center off Blake Parker after Chicago rallied to tie the game with a six-run sixth.
Lucroy's third-inning shot landed on Waveland Avenue, erasing the Cubs' early 3-0 lead. Lucroy also stroked a two-run single in the sixth and an RBI single in the eighth, matching the career high of seven RBIs he set May 20 against Minnesota.
Braun's league-leading 36th homer was even more impressive, clearing the batter's eye beyond the ivy in center field and nearly hitting the camera booth.

The Cubs win capped a lopsided season series between the NL Central rivals that saw Milwaukee take 13 of 17 games. Cubs manager Dale Sveum was a coach for the Brewers before taking the reins in Chicago.
Shaun Marcum was making his second start after missing two months because of elbow soreness. He allowed three runs, scattering five hits and four walks while striking out four.
Marcum had to leave the game after throwing 85 pitches because of right calf cramping.
Carlos Marmol (2-2) picked up the win in relief.
Cubs rookie Brooks Raley gave up seven runs and 10 hits in four innings in his last outing of the season. Before the game, Sveum said that Raley would be shut down because of an innings limit.
Raley will finish the season 1-2 with an 8.14 ERA in his first five big-league starts.
Brett Jackson, another rookie, reached base four times. He doubled twice in the sixth, including a slicing two-bagger up the left-field line that tied the score at 9-apiece.
David DeJesus and Luis Valbuena had three hits each for Chicago, which avoided falling 32 games under .500 for the first time since finishing the 2000 season 65-97.
