Konstantin Tszyu
Konstantin Borisovich "Kostya" Tszyuis a Russian-Australian former professional boxer who competed from 1992 to 2005. He held multiple world championships in the light-welterweight division, including the undisputed and lineal championships between 2001 and 2005. Tszyu was an exceptional all-around boxer-puncher who relied heavily on accuracy, timing, and carried formidable punching power; he is often regarded as one of the hardest-punching light-welterweights in the division's history, and one of the greatest light-welterweights of all time.
As an amateur, Tszyu represented the Soviet Union, winning a bronze medal in the lightweight division at the 1989 World Championships, and gold in the light-welterweight division at the 1991 World Championships. He also won consecutive gold medals at the 1989 and 1991 European Championships.
In 1995, Tszyu won his first of many professional world championships at light-welterweight—the International Boxing Federation (IBF) title—by defeating Jake Rodríguez. Five successful defences were made until an upset loss to Vince Phillips in 1997, which was Tszyu's first professional defeat. He would spend the next eight years undefeated, winning the vacant World Boxing Council (WBC) title in 1999 and the World Boxing Association (WBA) (Super version) title in 2001. Tszyu scored arguably his most famous win that year, when he knocked out Zab Judah to reclaim the IBF title, as well as the vacant Ring magazine and lineal titles, thus becoming the first undisputed light-welterweight champion in over 30 years. In 2005, in what would be his final fight, Tszyu was stopped by Ricky Hatton.
Tszyu is considered by many in Australia to be a national sports hero. In The Ring's March 2010 issue, Tszyu was ranked as the number one light-welterweight of the 2000s decade. In December 2010, he was inducted into the International Boxing Hall of Fame for the Class of 2011. From 2012 to 2013 he coached professional boxers Alexander Povetkin, Denis Lebedev and Khabib Allakhverdiev. In 2023, his son Tim Tszyu won the World Boxing Organization (WBO) junior-middleweight title.
