If your little Derek Jeter or David Wright fan is coming down with a case of Spring Fever, why not treat it with even more baseball-themed fun? For five days this summer, the Major League Baseball All-Star Fanfest transforms the Javits Center into the largest interactive baseball theme park in the world, featuring exhibits from the National Baseball Hall of Fame, batting cages, baseball clinics, autograph sessions with former Mets players and more. Sunday (July 14) is Taco Bell All-Star Sunday ($65-$108, includes admission to Fanfest). This includes the All-Star Futures game, which showcases top Minor League Prospects, and the All-Star Legends & Celebrity Softball Game, which features stars in music and entertainment teaming up with Hall of Famers and New York baseball greats. All ages.
