ST. LOUIS -- Pitchers dominated the first three games of the World Series, then rain took over.

Game 4 was postponed last night at Busch Stadium because of showers and will be made up at 8:27 p.m. today, potentially sending the World Series into scheduling chaos. More rain was expected the next two days, and nobody was certain when the Detroit Tigers and St. Louis Cardinals would play again.

"They're going to be dicey," said Jimmie Lee Solomon, executive vice president of baseball operations in the commissioner's office. "There is about a 70 percent chance of rain [today]. It's going to be light rain. We don't know whether or not that rain will linger, like it did tonight."

Game 5 at Busch Stadium was pushed back to tomorrow night, which was supposed to be a day off in the Series. And it doesn't look much better this weekend in Detroit, with a forecast of rain and cold.

The Cardinals lead the best-of-seven series, 2-1, after a 5-0 victory behind ace Chris Carpenter Tuesday night. A silver tarp covered the infield all evening, players didn't come out to warm up and Game 4 never got started.

"This wouldn't have been a baseball game, it would have been survival," St. Louis manager Tony La Russa said. "I'm actually pleased for both teams that we're not playing. Fans, that wouldn't have been too much fun, either."

But Jeremy Bonderman, slated to start for Detroit against St. Louis' Jeff Suppan, was eager to pitch in the light drizzle last night.

Both are scheduled to start again tonight.

Tigers first baseman Sean Casey, however, thought Major League Baseball made the right call.

"Guys getting hurt, having a five-inning World Series game, nobody wants that," Casey said.

Steady showers all day led to the first World Series rainout since the 1996 opener between the Braves and Yankees. The rain fell harder as the night progressed, and the game was called after a delay of 1 hour, 51 minutes, the first time a World Series game in St. Louis has been rained out.
