Also known as The Legend, Frank Shamrock has done a lot of great things for the sport as a fighter and an ambassador. He last fought in 2009 and finished his career with a record of 23-10-2. During the course of his 17-year career, Shamrock fought the biggest names in the sport and earned victories against the likes of Tito Ortiz and Bas Rutten. After beating Kevin Jackson in 1997 to win the UFC Light Heavyweight title (then known as Middleweight title), Shamrock would defend the title on four occasions before relinquishing the title and retiring. Following his retirement, he would return to win the Strikeforce Middleweight title and the World Extreme Cagefighting Light Heavyweight title.
