Gathering in large groups and vociferously chanting expletive-filled songs in support of their favorite players, several groups of rival PGA hooligans violently clashed at the Augusta National Golf Club during the final round of the Masters Sunday, sources confirmed. Theyre here every tournament waving banners and inciting trouble all over the course, but this years fights were particularly bad, Augusta chairman Billy Payne told reporters, noting that the roving bands of die-hard golf enthusiasts left a trail of mayhem that included throwing garbage cans through the Augusta pro shop windows, overturning several ball washers and setting them on fire, and leaving various unfilled divots throughout the course. Early in the day on the fifth hole, a group of Stewart Cink supporters tangled with some of the McIlroy Boys in a nasty brawl that spilled out from the gallery onto the green. Then someone from the Furyk Crew chucked a lit flare at Vijay Singhs caddy, and at that point we just had to suspend play and call in the paddy wagon. According to officials, this years fights were the worst since a vicious melee at the 2009 Masters in which dozens of berserk, intoxicated hooligans swarmed and savagely beat a defenseless Phil Mickelson into a coma.
