Here’s projected Cubs pitching rotation for the next few games:
* Carlos Zambrano (1-3, 6.12 ERA) returns to rotation Friday night vs. Astros. He’ll be followed by Ryan Dempster (3-5, 3.72 ERA) on Saturday and Randy Wells (3-3, 4.40 ERA) on Sunday.
* Carlos Silva, who has yet to face the Pirates this year, will start Monday in the makeup game in Pittsburgh. Silva is off to his best start ever at 7-0 with a 3.12 ERA.
* Ted Lilly (1-5, 3.61 ERA), who has faced the Pirates three times this season, will open the Cubs series in Milwaukee on Tuesday.
