CHICAGO -- Ozzie Guillen had one of his unique theories as to why Tuesday's opener of the Crosstown Showdown at Wrigley Field was covered by a deluge of rain, eventually leading to the first cancellation in the 13 years of the Interleague series between the Cubs and the White Sox.

"God is punishing me to have a rain delay in this place," said a smiling Guillen, not exactly a fan of the Wrigley working conditions.

That punishment could be slightly more severe for Guillen and the White Sox, with another date on the North Side now added to the schedule. Doubleheaders on either Wednesday or Thursday were ruled out, leaving mutual open days on Thurs., Sept. 3 or Thurs., Sept. 10 for this contest to be made up.

If the White Sox find themselves in contention for the American League Central title at that point, and the game is played on Sept. 3, check out this competitive stretch for the South Siders.

From Aug. 24-27, they have four games in Boston. From Aug. 28-30, they have three games at the new Yankee Stadium. And from Aug. 31-Sept. 2, the White Sox play in their own personal house of horrors known as the Metrodome. The Cubs game could slide in to extend this treacherous 10-game road trip to 11, followed by four games at home against Boston.

A makeup on Sept. 10 would come a day before the White Sox embark on a six-game road trip to Anaheim and Seattle.

For now, the White Sox focus remains on these next two day games at Wrigley. Ryan Dempster gets the call for the Cubs on Wednesday, with Carlos Zambrano moving back from his Tuesday start to Thursday.

Everyone in the White Sox rotation moves back one day, with John Danks and Gavin Floyd facing the Cubs, and Jose Contreras, Clayton Richard and Mark Buehrle going against the Reds in Cincinnati. The rotation order will be re-evaluated following Monday's off-day.

"We will reassess, readjust and see if we're going to make any changes," White Sox pitching coach Don Cooper said. "The bottom line is we're pushing things back.

"In some ways it's good, in some ways it's not. We already had an off-day. So this just gives everybody an extra day's rest. It depends on how you look at it. I think we're going to be sharp anyways. It's not going to affect our sharpness, I don't believe. We're not going to use that as an excuse, the extra day.

"They're all going to get their 32 starts and everything like that," Cooper said. "I don't think it's much of a factor. The bottom line is we've got to work with what's going on. The weather wasn't cooperative."

Fans should retain their tickets from Tuesday's game until further information is available regarding ticket policies for the to-be-scheduled makeup game. One benefit for the White Sox coming from Tuesday's postponement is that they should have Carlos Quentin back in left field by the time the game is made up in September.

Quentin continues to take small steps toward a return from a bout with plantar fasciitis in his left foot. It was a recovery pushed back when Quentin believes a pop he felt rounding first during a first-inning double on May 25 in Anaheim represented the tearing of his tendon.

Guillen sounded about as optimistic for a quick Quentin return as he sounded excited to be playing in Wrigley Field.

"I wish I could have really positive news, but I can't because ... ," said Guillen of Quentin. "Carlos is making progress? Yes. No doubt about it. He gets better every day? No doubt about it. But I cannot say he got better, because I don't see him running -- doing baseball stuff. Just shagging in the outfield like normal.

"In my opinion, I've made up my mind about him not in the lineup until the All-Star break. That's what I got in my mind. Hopefully he gives me a nice surprise and says I'm ready to go in one to two weeks. But right now, I cannot think about him because I don't want to get hurt later. When he's ready, he's ready. When he's ready, he's ready for good. But I'm not pushing him. I don't think I should. I don't see him get back in the lineup every day soon.

"You say he's going to be here, and all of a sudden he's not," Guillen said. "You're going to blame that because we're not playing well. He comes back? Good. If not, we have to deal. But you have your hopes, and then it breaks your heart and enthusiasm. Just don't count on him until he's here."
