CINCINNATI -- An unprecedented matchup of birthday-celebrating starters came down to the bullpens. Carlos Marmol got a little wild, lost a three-run lead and, perhaps, his job as well.
The Reds needed a lot of help to pull it out, and got it.
"It didn't look good there for a while," said Rolen, who got most of the day off but came in at third base to start the 10th. "After we came back to tie the game, the only thing left is to finish it."
Marmol spoiled a big moment for Ryan Dempster, who returned from the disabled list and pitched eight shutout innings on his 35th birthday. He allowed only three hits and was in line to get his first win since Aug. 11.
Dempster got the better of Homer Bailey, who turned 26 on Thursday. It was the first time in major league history that both starters were celebrating a birthday, according to information provided by the Reds, citing the Elias Sports Bureau.
Both pitchers signed baseballs for the Hall of Fame.
"That's something neat," Dempster said.
The Reds stood at the plate and watched Marmol self-destruct in the ninth. He walked Willie Harris and Joey Votto on nine pitches to open the inning. An error by Ian Stewart -- the third baseman rushed trying to turn a double play -- let in a run.
Jay Bruce singled to load the bases, and Marmol walked Ryan Ludwick to force in a run that made it 3-2 and ended the closer's outing. Rafael Dolis (1-2) relieved and got a double play that left it tied at 3.
Marmol threw 18 pitches, only six of them strikes.
"Sometimes he's throwing strikes, and then he's practically unhittable," Reds manager Dusty Baker said. "The key is to swing at strikes and make him throw balls. We don't have a whole lot of guys who hit him well."
Marmol has blown three of his five save chances, walking 12 in 8 2/3 innings. Manager Dale Sveum said after the game that he'll consider moving him out of the closer's role.
"You have a game like that -- I'm embarrassed right now," Marmol said.
Another error helped the Reds win it. Zack Cozart singled in the 10th off Dolis, who then threw wildly to first base on Chris Heisey's sacrifice attempt. Rolen followed with his sacrifice fly to deep right field. Logan Ondrusek (2-0) pitched the 10th.
LaHair has provided the bulk of the Cubs' power this season, hitting seven of their 14 homers. Chicago hit only nine in April, fewest in the majors, but had five in the two games at Great American Ball Park -- all of them solo shots.
Chicago now has homered in a season-high four consecutive games.
Dempster's long winless streak -- now 13 games -- is partly due to a lack of support. He'd allowed only three earned runs in three starts this season before hurting his thigh, but the Cubs scored a total of four runs in those games. He lowered his ERA to 0.95 with the eight shutout innings.
It was the second year in a row that he pitched well on his birthday and failed to get a win. Last year, he allowed only one run over seven innings and got a no-decision in a 4-1 win over the Dodgers.
The Cubs also activated reliever Kerry Wood off the disabled list before the game. He'd been sidelined with fatigue in his pitching shoulder.
