Instead, it will be Angel Guzman, a Sept. 1 call-up who has appeared in only five games -- all Cubs losses -- and has a 7.04 ERA in 7 2/3 innings.
Cubs manager Lou Piniella said Zambrano told team officials he'd rather throw a side session in the bullpen instead of working the first couple of innings Sunday. If Zambrano had started, he would have been pitching on three days' rest.
Piniella rested most of his starting lineup in Saturday's 7-3 victory, but said he would start his regulars Sunday against lefty CC Sabathia.
I think it would be hilarious if the Cubs beat the Brewers with Guzman pitching.
