Carlos Marmol was back on the mound trying to close this one out, and once again, he came up short. The Cubs did not.Ryan Dempster pitched four-hit ball over eight scoreless innings, and the Cubs overcame another shaky performance by its closer to beat Florida 2-1 Friday, snapping the Marlins’ season-high, six-game winning streak.Dempster (7-6) struck out nine without a walk in probably his best outing of the season as the Cubs won for the third time in nine games, but the focus again centered on Marmol.Right now, that part isn’t working.After the closer’s ninth-inning meltdown Thursday, Quade had said he wasn’t sure he would use Marmol in a save situation, but he did after talking to the pitcher, coaches and management before Friday’s game.That backfired when they turned to Marmol in the ninth Friday and he again didn’t make it out of the inning. Sean Marshall got out of the jam and will close for the next few days.Marmol came in to boos on the heels of a miserable performance in which he walked four of the five batters he faced and failed to record an out. The Marlins scored six in the ninth to win that one 6-3 and they nearly pulled off another comeback Friday.Marmol’s latest troubles began when he walked Omar Infante on four pitches to start the inning.He caught a break with one out when center fielder Marlon Byrd threw out Hanley Ramirez trying to stretch a single into a double.Quade would have lifted Marmol then had Ramirez not been thrown out. Instead, he watched as Logan Morrison lined an RBI single to right, cutting Florida’s deficit to 2-1.Marshall relieved Marmol and struck out Mike Stanton to end the game, giving him two saves in four chances.He insisted the problems are mechanical, not mental, and that he still has his confidence. What he doesn’t have is his control or patience from the fan base.The Cubs took a 2-0 lead in the fourth inning when Infante misplayed Alfonso Soriano’s pop fly to second base, allowing Carlos Pena and Byrd to score.That was just enough for Dempster and the Cubs.Ricky Nolasco (6-6) pitched about as well as Dempster but took a tough loss.Nolasco allowed two unearned runs and seven hits, and struck out seven and walked one in seven innings. It was another strong performance following his complete-game win over Houston on Saturday. He also doubled off the wall with two outs in the third, but the Marlins couldn’t do much against Dempster.Nolasco ran into trouble in the fourth when Pena singled with one out and Byrd doubled, but he struck out Geovany Soto and should have gotten out of the inning when Soriano popped up.Infante raced out toward right field, and slowed as Stanton came in. The ball appeared to tip his glove and fell in for an error, allowing both runners to score.McKeon said it was an easy play for Stanton and he should have made that catch.

NOTES—The Cubs agreed to a minor league deal with veteran pitcher Dave Bush….Cubs first base coach Bob Dernier missed the game to attend his son’s wedding in Kansas City. He is expected back Sunday. Dave Keller, special assistant to Quade, filled in.
