Rain postpones NLCS opener

NEW YORK – The New York Mets might have to face Chris Carpenter sooner than expected.

Game 1 of the NL championship series between New York and St. Louis was postponed Wednesday night because of a steady rain, giving the Cardinals a chance to pitch their ace on full rest in Game 2.

The best-of-seven series will now begin tonight, and Game 2 at Shea Stadium is to be played Friday – which was supposed to be an off day in the series.

Carpenter had been slated to start Game 3 on Saturday, when the series shifts to St. Louis. But the 2005 N.L. Cy Young Award winner would be working on his regular four days of rest if the Cardinals decide to bump him up to Friday.

“That is his fifth day. You’ve got to seriously think about what that means. It’s up for grabs in my opinion,” St. Louis manager Tony La Russa said. “My first 30-45 minutes of looking at it, I said I’d probably stay with it. Sitting here for 15, there’s more there. There’s a decision to make, no doubt about it.”

The Mets will stay with Tom Glavine in the opener, and the 40-year-old left-hander said he expects to come back and pitch on three days’ rest in a Game 5.

“I’ve done it before. I know what to expect, how to prepare from tomorrow’s start to my next start knowing it’s going to be on short rest. But you still have to go out there and do it,” Glavine said. “The most important game for me is tomorrow, and trying to win that game for us – then worry about starts I may have after that.”

Jeff Weaver was to get the ball for St. Louis in Game 1, as originally planned.

The Mets and Cardinals will play five straight days now.
