They didn't win. They lost Carlos Marmol to a hamstring injury. They hammered their bullpen. And they played so long that Friday turned into Saturday morning, which turned the first two games of this series into what amounts to a doubleheader.

''That was a great game, though,'' Cubs manager Dale Sveum said after Corey Hart's ground-ball single up the middle off the Cubs' last reliever, Lendy Castillo, drove in the winning run in the 13th inning as the Milwaukee Brewers beat the Cubs 8-7.

''Obviously, we finished on the bad end of it, but that was one heck of a game to watch and be a part of on both sides.''

Marmol strained his left hamstring on his final pitch of the seventh inning, a slider to Hart. He threw two practice pitches in an attempt to stay in the game but was taken out. After the game, he was preparing to return to Chicago on Saturday for an MRI exam.

He's expected to go on the 15-day disabled list, a move made all but necessary by the seven-plus innings the bullpen was forced to throw, including two innings each by Rafael Dolis and Kerry Wood.

Asked how bad it was, Marmol said, ''I don't know. It hurts. I'll have the MRI [Saturday], and we'll see.''
