CHICAGO -- The Saturday doubleheader between the White Sox and Tigers at U.S. Cellular Field was postponed due to rain. The two teams will play a split doubleheader on Sunday.

With Friday's game also being rained out, only two of the three games between the clubs will be completed this weekend, weather permitting. Since the Tigers and White Sox don't share an off-day in common, the final game will likely be rescheduled after the regular season, if it is even necessary to play.

Game 1 on Sunday will begin at 1:05 p.m. CT and be televised by Comcast Sports Net, while Game 2 will begin at 7:05 p.m. on ESPN.

Javier Vazquez was set to pitch the matinee on Saturday, but will instead do so in the first game on Sunday against Justin Verlander. The extra day might be a good thing for Vazquez, who was to throw on short rest Saturday.

"I don't know if it's good or bad, because I changed my program to pitch on three days' rest, not four days," Vazquez said. "But my arm feels good today and it will feel good tomorrow, so no big deal. It will feel good Monday, too. Hopefully, we can get both games in."

Early forecasts for Sunday indicate more rain in the afternoon.

"It's not going to be any better tomorrow," White Sox manager Ozzie Guillen said. "It's something I don't worry about, because I can't control that. If it's going to be bad tomorrow -- the forecast -- then we'll see how that plays out later on."

Fans with tickets to Saturday's 2:55 p.m. contest may use those tickets for Sunday's first game, or they may exchange those tickets for upper-level seats to any home game in April 2009 (excluding Opening Day, based on availability). All exchanges should be made at the U.S. Cellular Field Box Office, either by mail (333 W. 35th Street, Chicago, IL 60616) or in person.

Gates to the ballpark will open at approximately noon for the 1:05 p.m. makeup game on Sunday.

John Danks will pitch Game 2 of the split doubleheader, facing Tigers starter Kenny Rogers. Danks was originally scheduled to pitch Friday night's opener.

The White Sox have lost four of their last five, so a break in the action could work in their favor. Outfielder Nick Swisher seemed more than happy to have the rest of Saturday to himself.

"I'm ready to go home and sleep and watch the Buckeyes play tonight," he said. "If anybody needs me, that's where I'll be."
