The Cubs plan to move up ace Carlos Zambrano a day to pitch tomorrow's series opener at Philadelphia, taking the spot of Jason Marquis, who's still recovering from the flu. Zambrano will be pitching on his natural fifth day because of this week's off day.
Manager Lou Piniella said Wednesday he wanted to swap tonight's starter, lefty Rich Hill, with Marquis if Marquis was well enough to go tonight.
Instead, Marquis -- who was to be in the bullpen tonight in case of emergency-- will be backed up to Sunday at the earliest, with lefty Ted Lilly going Saturday.
Piniella said eithe Marquis or left-hander Sean Marshall will start Sunday.
