Mezin left his native Belarus in 1993 to head to North America and would spend five seasons playing in different leagues, including the
American Hockey League, the
International Hockey League and the
United Hockey League. From 1998 to 2002, he played in Germany: one year with the
Nürnberg Ice Tigers and three with the
Berlin Capitals. He then played in Russia and the Czech Republic. Starting 2008, he spent time with KHL teams
HC Dinamo Minsk,
Lokomotiv Yaroslavl,
Traktor Chelyabinsk and
Avangard Omsk. Mezin gained international attention in 2002 as a member of the
Belarus national men's ice hockey team at the
2002 Winter Olympics. Despite not winning a game in the Group D round robin, Belarus beat the
Sweden national men's ice hockey team in the quarterfinals. Mezin was stellar, holding a star-laden Swedish team to three goals on more than 50 shots. The game was won by Belarus late in the third on a long shot gaffe made by
Tommy Salo in the Swedish net. Belarus ended up finishing in fourth place after losing to Canada in the semifinals. Mezin has represented the Belarus national team at the 1998, 2002 and 2010 Olympic Games and played several World Championships. On 1 October 2008 Mezin and Metallurg Magnitogorsk faced the
New York Rangers of the NHL in the
inaugural Victoria Cup. Mezin stopped 40 out of 44 shots, playing a very respectable game in the 4–3 loss. Mezin retired in 2014. == Coaching career ==
