Roy Halladay called it a career last month. But Halladay is keeping busy in retirement, dominating the 1980s party costume game. A 1986 Jamie Moyer Cubs uniform. Classic.
No debate here. That's a Hall of Fame-caliber costume.
UPDATE: Phillies stars Ryan Howard and Jimmy Rollins also attended the party.
