NEW YORK - Johan Santana arrived at Shea Stadium on Wednesday, put on his No. 57 New York Mets jersey for the first time and said he anticipated little difficulty in adjusting to pitching before some of baseball's most demanding fans.

“I think the game is the same,” he said. “I'm not going to let that affect what I do on the field.”

The Mets introduced Santana with a choreographed news conference, one that began with video highlights and Latin music. After an extended period for still and video cameras, and a brief statement by Santana, the Mets turned up the house lights of Shea Stadium's Diamond Club for questions.

Santana answered many with cliches, speaking how he would take things one day at a time, that success was a team effort and that he will have to make adjustments to pitching in the National League. He understands that Mets' fans demand a World Series championship - or at least an NL pennant - immediately following last year's September collapse.

“Of course, it has to be this year and beyond,” he said.
