Xavier Nady drove in the go-ahead run in the ninth to cap a rally from a three-run deficit and lift the Chicago Cubs to a 4-3 victory over the Pittsburgh Pirates on Sunday.

The Cubs scored twice in the seventh, tying it at three on Derrek Lee's RBI single. Nady gave them their only lead of the day with a pinch-hit single in the eighth to make a winner of left-hander Sean Marshall.

Marshall (2-1) worked a scoreless eighth in relief of Ted Lilly, and Carlos Marmol struck out two in a perfect ninth for his sixth save.

Lilly threw seven innings, giving up three runs on six hits and three walks with four strikeouts.

D.J. Carrasco (1-1) took the loss for Pittsburgh, which had its seven-game win streak against the Cubs snapped.

The Pirates took a 3-0 lead in the second on an RBI single by Bobby Crosby and a two-run single by Lastings Milledge, but they couldn't hold the lead for starter Ross Ohlendorf.

Ohlendorf went six-plus innings, allowing two runs on four hits.
