Chicago ? Aramis Ramirez hit a three-run homer off reliever Brett Tomko in the seventh inning Thursday, and the Chicago Cubs rallied for a 6-5 victory that reduced the Los Angeles Dodgers’ lead in the NL West to a half-game.

The Dodgers headed home after losing two of three at Wrigley Field to the Cubs, who are 29 games under .500. Los Angeles begins a key four-game series today with second-place San Diego.

J.D. Drew’s three-run homer off Carlos Marmol gave the Dodgers a 5-2 lead in the sixth and put Hong-Chih Kuo in position to win his second straight start.

But Tomko (8-7) was roughed up. Ronny Cedeno’s single, a bunt single by Juan Pierre and a two-out RBI single by Ryan Theriot made it 5-3. Ramirez followed with his 33rd homer, giving him 100 RBIs for the season.

Scott Eyre (1-2) got the win with 12â3 innings of hitless relief.
