PHILADELPHIA -- The dates for Games 6 and 7 of the World Series schedule, if necessary, are still to be determined after Major League Baseball moved the resumption of Game 5 of the World Series tentatively to Wednesday night at 8:37 p.m. ET in Citizens Bank Park because of continued inclement weather in Philadelphia.

If the Rays were to win Game 5, which stands tied at 2, the Fall Classic will return to Tropicana Field in St. Petersburg, Fla. The question is when. Games 6 and 7 originally were scheduled for Wednesday and Thursday, but will need to be pushed back with the resumption of Game 5 now tentatively set for Wednesday.

"Nope, nope there's nothing new, right now," said Bob DuPuy, MLB's president and chief operating officer on Tuesday after the game was postponed for the second time. "Let's get Game 5 out of the way and then we'll worry about it."

DuPuy called the resumption of play on Wednesday night "problematic," even though the weather is supposed to be better.

"It's going to be less wet, less windy and less cold than today, but it's still problematic," he said. "The Commissioner wants to avoid what happened last night and that the game is finished with full integrity.

"We're continuing to look at it on a day-to-day basis."

Wednesday's tentative 8:37 p.m. start time is locked in, because MLB had previously agreed to push Game 6 back eight minutes so Fox could show a paid half-hour presentation by Democratic presidential candidate Barack Obama to be shown from 8-8:30 p.m. The program is being simulcast on three of the major networks.

World Series Game 5 tickets will be required for re-entry when the game ultimately does resume. There has never been a rain-shortened game in Series history, and this was the first suspension.

DuPuy said fans were given ample notification on Monday night to retain their tickets in case of a rainout or suspension. Traditionally, stubs are needed to obtain tickets to another game during the regular season.

"Our tickets say that," he said. "The club announced it. They announced it as soon as we went into the delay. It went up on the board, and they announced it again when the game was suspended. I think the club handled it very well, and I hope that the fans did in fact hold their tickets."
