No one is safe, not even the best pros in the world. Three-time WSOP bracelet winner Mike "The Mouth" Matusow takes center stage on opening day and brings plenty of entertainment and intensity. "The Mouth" has made some of the most memorable deep runs in the modern era of the Main Event, and this year he's as hungry as ever to get another shot at the title. But he’ll have to contend with a monstrous field that features some of the biggest names in the game, including 2003 champion Chris Moneymaker, 2004 titlist Greg Raymer and 2010 Poker Players Championship winner Michael "The Grinder" Mizrachi. Others in action on opening night include WSOP Europe winner Annette Obrestad, former Main Event champion Dan Harrington and 2008 Player of the Year Erick Lindgren.
