Siarhei Mikalaievich Borchanka (Belarusian: Сяргей Мікалаевіч Борчанка; born January 30, 1976, in Grodno) is a retired amateur Belarusian freestyle wrestler, who competed in the men's light heavyweight category.[1] He finished fourth in the 84-kg division at the 2003 World Wrestling Championships in New York City, New York, United States, and later represented his nation Belarus at the 2004 Summer Olympics. Borchanka also trained as a member of the freestyle wrestling team for Dynamo Hrodna, under his personal coach Stsiapan Buikevich.[2]
Borchanka qualified for the Belarusian squad in the men's light heavyweight class (84 kg) at the 2004 Summer Olympics in Athens, by placing fourth and receiving a berth from the World Championships a year earlier.[3] Borchanka dismantled Kazakhstan's Magomed Kurugliyev on his opening bout with a 2–1 decision, but could not push U.S. wrestler and 2003 world silver medalist Cael Sanderson off the mat, and suffered a defeat by a 1–9 blowout at the end of the tournament.[4] [5] Finishing second in the prelim pool and fourteenth overall, Borchanka's performance fell short to put him through to the quarterfinals.[6]
