Giorgio Petrosyan emigrated to Italy from Armenia at age 13, and began his muay thai career three years later. After a loss in January 2007, he went on a six-year, forty-two fight undefeated streak considered to be the most dominant reign in the history of the middleweight division which was eventually ended by Andy Ristie at Glory 12: New York in November 2013.
During that streak, he defeated some of the top fighters including Mike Zambidis, Albert Kraus, Andy Souwer, Naruepol Fairtex, Ky Hollenbeck, Davit Kiria, and Robin van Roosmalen.
He was also a two-time K-1 Max World MAX World Championship tournament winner in the 154 lb division, WMC welterweight champion, and Glory 70kg Slam champion in 2012, among other international accolades.
To date, Petrosyan’s last fight in Glory was Glory 25 in Milan, where he defeated Canadian Josh Jauncey by unanimous decision in 2015.
