Could the Orlando Magic have been hurting from the night before during their 108-86 beating by the Knicks on Wednesday? The previous night, sources spotted the Magic’s Glen “Big Baby” Davis and Jason Richardson partying until the early hours. They started out dining in the private wine room of Philippe New York. Then the pair joined Dwight Howard — who got a shout-out from the DJ on the loudspeaker, spies said — Chris Duhon and Quentin Richardson at Greenhouse during R&B singer Dawn Richard’s EP release party. The players were seen ordering bottles of Champagne and raged in the club until around 3 a.m. The next day, sources told us, they looked “horrible” during their pregame shoot-around, missing most of their practice shots. They later looked slow-footed during the game. Celebs who took in the Knicks’ victory included Kate Upton, Jeremy Piven, Aziz Ansari, Vincent Piazza, and New York Giants Justin Tuck and Victor Cruz. A Magic rep didn’t return calls.
