If Carlos Marmol can be effective again as the Cubs' closer, it will have a ripple effect on the bullpen.

''You have a guy who's done it before, and you get him on track again to throw strikes; that's all you want,'' manager Dale Sveum said.

In the process, James Russell, Shawn Camp and Casey Coleman can return to the setup roles they're more suited for, Sveum said.

On Friday, Marmol earned his first save since May 2 even though he loaded the bases before getting a force out to end the game.

Sveum said Marmol looked confident in his previous appearance, Tuesday against the Detroit Tigers.

''I told [pitching coach Chris] Bosio it was the first time he came to the mound with that look of 'Let's go,' and you could see the correlation when he was throwing,'' Sveum said.
