St. Louis ? The weather on Tuesday afternoon at Busch Stadium was unseasonably warm — about 80 degrees with the sun shining, though there was a brisk wind.

It sure won’t be like that for Game 6 tonight.

The forecast is for temperatures in the 40s, with a 50 percent chance of showers. That’s actually an improvement over initial forecasts that called for an 80 percent chance of rain.

“We want to make sure conditions are correct, and if we have to wait a day, we’ll wait a day,” Rangers manager Ron Washington said. “But if it’s possible to play, I want to play.”

Asked whether postponing Game 6 would allow ace Chris Carpenter to pitch a deciding Game 7 on three days’ rest, if necessary, Cardinals manager Tony La Russa just smiled and said that although he absolutely wants a Game 7, he wants to be focused on Game 6 first.
