Just in time for the Subway Series, Delta Air Lines will host three different events for area baseball fans, including giveaways, chances to meet Yankees and Mets players and games. On Friday, play trivia games, practice your swing and check the speed of your pitch. On Saturday, meet Mr. Met and see Bernie Williams. On Sunday, dress to impress in your best team attire for a chance to win tickets to future games and more. All ages.
