In a last-ditch effort to land the 2012 Olympics, the city will substitute a planned baseball stadium for the football stadium rejected by state leaders earlier this month, Mayor Michael Bloomberg said yesterday.

Bloomberg said the new stadium would be built on land owned by the city next to Shea Stadium in Queens and would be used by the New York Mets. He said he was committed to fighting for the 2012 Summer Games despite the recent setback.

"New Yorkers aren't quitters," he said. "We just don't walk away from our future."

Bloomberg said the Mets will build the stadium, which will be privately funded, for the 2009 season. The city and state will provide $160 million in infrastructure, he said.

Bloomberg and his NYC2012 bid committee worked through the weekend to finalize the revised plan, which could be presented to the International Olympic Committee next week. The IOC will choose a host city July 6 in Singapore.

The city is competing against Paris, London, Madrid and Moscow to host the Games.

On June 6, state leaders refused to approve $300 million in funding for a proposed $2.2 billion football stadium on Manhattan's West Side. The stadium was to have been used primarily as the home of the New York Jets.
