On the road back

Cubs minor-league pitching coordinator Mark Riggins told general manager Jim Hendry that Carlos Zambrano looked "a little rusty" on Sunday when he pitched for the Class A Daytona Cubs.

Hendry said Zambrano threw the right amount of pitches (67), covered first base well and is set to meet the team Tuesday in St. Louis. The plan is for Zambrano to throw a side session on Wednesday with pitching coach Larry Rothschild and trainer Mark O'Neal present.

Zambrano is expected to start for the Cubs on May 22 in San Diego, if everything goes according to plan. He hasn't started for the big-league team since May 3, when he injured his left hamstring beating out a bunt single.

Hendry also said Zambrano would do some light running with strength and conditioning coach Tim Buss and O'Neal. Zambrano is scheduled to have two days of fielding practice, which includes fielding regular ground balls and covering first base in special drills.
