Wild Cubs closer Carlos Marmol helped Cincinnati rally for three runs in the ninth to tie it, and Scott Rolen hit a sacrifice fly in the 10th inning that swept the Reds to a 4-3 victory Thursday and two-game split.
Marmol let a 3-0 lead slip away by walking three of the five batters he faced, allowing Cincinnati to tie it with only one hit in the inning. It was his third blown save in five chances. Marmol has walked 12 batters in 8 2-3 innings.
Rolen won it against Rafael Dolis (1-2), whose wild throw to first on Chris Heisey's sacrifice attempt set up the winning run. Logan Ondrusek (2-0) pitched the 10th.
Marmol's struggles decided the first matchup of starters celebrating birthdays in major league history.
