Last night BAT, the Baseball Assistance Team, the charity that helps needy former players, held its annual fundraising banquet in New York. Dozens of baseball celebrities were on hand, including many Mets -- whose 50th anniversary was the evening's theme. The emotional high point occurred early in the evening when this remarkable collection of 13 Hall of Famers assembled on stage for a group photo: (Top Row - left to right) Tom Seaver, Sandy Koufax, Gaylord Perry, Phil Niekro, Goose Gossage, Orlando Cepeda, Luis Aparicio. (Middle Row) Mike Schmidt, Jim Palmer, Joe Morgan, Juan Marichal. (Front Row) Tony Perez, Willie Mays. Short of the annual inductions in Cooperstown, where will you ever see such a collection of all-time talent?
