A Black Belt in Brazilian Jiu-Jitsu and a Victoria State Amateur Boxing Champion, George Sotiropoulos has established himself over the past several years as one of the very best Australian professional mixed martial artists, and a budding star.

After running his professional record to 7-2 prior to joining The Ultimate Fighter 6 Welterweight Tournament in 2007, Sotiropoulous’s only career defeats had come to Kyle Noke—who competes in the middleweight division—in a decision loss he has since avenged, and a DQ loss to Shinya Aoki after kicking Aoki in the groin.

While he did not win The Ultimate Fighter 6 after being poked in the eye by Tommy Speer in the Semifinals of the show, Sotiropoulos did earn a win in his first official bout with the UFC after submitting Billy Miles with a Rear Naked Choke. Sotiropoulos went on to finish his next three UFC opponents before earning the biggest win of his career by defeating former top contender Joe Stevenson by Unanimous Decision in their match from UFC 110. The Stevenson match was held during the UFC’s first event in Sydney, Australia, and resulted in absolute crowd delirium as Sotiropoulos imposed his will on Stevenson throughout the fight, and got the better of a number of standup exchanges. In his next fight, the surging Sotiropoulos was paired with the equally hot Kurt Pellegrino to see which man would keep his winning streak alive. In a smooth, professional performance, Sotiropoulos took the decision, stifling "Batman's" offense for most of the affair.

Sotiropoulos is best known for his aggressive and relentless Jiu-Jitsu style, including some of the most fluid guard passing in the UFC as well as a highly effective rubber guard. But Sotiropoulos also calls on an amateur boxing background to damage opponents with a rangy jab before taking the fight to the floor and looking for the submission.
