The third game of Major League Baseball's best-of-seven championship series, which is tied at 1-1, will now be played on Tuesday with the remainder of the games and the travel day back to Houston, if necessary, also pushed back by a day.
The Astros were set to send right-handed pitcher Lance McCullers Jr. to the mound for Monday's game while the Phillies were going to counter with right-hander Noah Syndergaard.
Phillies left-hander Ranger Suarez will now start Tuesday's contest while the Astros will stick with McCullers as their Game Three starter.
Astros manager Duty Baker said his team would treat Monday as a regular off day and players would get treatment and some extra betting practice in to get ready for Tuesday.
"So you just got to turn it off and then get a good night's rest," Baker told reporters. "It's part of the game. You can't control the weather. So you just deal with it."
The fourth and fifth games will now be played on Wednesday and Thursday and, in the event the series has not been decided, Friday will be a travel day back to Houston.
A potential Game Six would be played on Saturday - which would make it the latest World Series game in terms of date - with a decisive Game Seven, if necessary, set for Sunday.
