Also pictured are radar gun operator Brett Weber as The Joker (Nick Swisher did the makeup), video coordinator Anthony Flynn as Robin, and and massage therapist Lou Potter as the Penguin. The guys had to wear their costumes past airport security, which of course is part of the embarrassing fun.
CC Sabathia took the whole group out for a steak dinner in California after the club landed around 9 p.m. PT, and some of the veterans like Andy Pettitte came along for the fun. The catch was that the guys still had to eat in their costumes (relaxed dress code, much?), though the Yankees did at least let Pena take off the mask so he could enjoy his meal.
