Granderson to Switch to No. 3 With Mets LAKE BUENA VISTA, Fla. - Outfielder Curtis Granderson had been the true image of a Yankee for four years: clean-cut, well spoken and productive. But he was introduced as a Met here Tuesday, one of the very few front-line players to go directly from one New York baseball team to the other while still a significant regular player. He said he had always been told, "True New Yorkers are Mets fans." As he delivered the line, he stood at a lectern, grinning and wearing his new No. 3 jersey. He said he chose the number because he was born in March, not necessarily because he envisioned himself as the Mets" Babe Ruth. The Mets, he said later, were the most aggressive team pursuing him and the only team to offer a four-year deal. He indicated he wanted to stay in New York, in part, to continue his charity work here. The Mets and Granderson agreed to his $60 million deal last week.
