Spike Lee celebrates with son Jackson at Yankee Stadium yesterday while showing off a new souvenir — a wayward bat that had just nearly whacked them.

Yank Mark Teixeira had accidentally sent the bat flying into the first row as he took a wild swing at a fastball in the game against the Angels. As spectators dived for cover, the director and city sports fanatic leaped up and let it sail into his seat. Alas, the Angels won, 10-8.
