Sergio Wielzen
Encyclopedia
Sergio 'Kleintje' Wielzen (born November 1, 1986 in Suriname
) is a Dutch
based Surinamese super lightweight
Muay Thai
kickboxer fighting out of Amsterdam, Netherlands for Black Label and FF Carbin. His nickname in Dutch is 'Kleintje' - which translates as 'Little One' in English. Despite his deceptively small stature he is known for his explosive power - having won many of his fights by KO
or TKO. He is the former (and first ever) It's Showtime 61MAX world champion.
Sergio moved to the Netherlands
where he became involved in the Dutch national Muay Thai
scene beginning his career at C-Class. An explosive fighter despite his short stature, Sergio worked his way up through the ranks finishing many of his opponents and was becoming noticed as one of the top young prospects at -61 kg in the Netherlands. In 2007 he met fellow up and coming fighter, Mohammed 'Mootje' Kamal
, coming out on top in what would be the biggest victory in his career up to that point, winning by decision after five rounds in their B-Class clash. The two would meet again in a re-match the following year, this time at A-Class level. Although Sergio suffered a TKO defeat, he also proved that he had an excellent chin, being knocked down time and time again before the referee finally stopped it in the fourth.
Sergio would truly emerge on the international scene in 2010 when he faced Thai legend Anuwat Kaewsamrit
in Geneva, Switzerland. In a match he was considered a clear underdog, Sergio shocked the Muay Thai world by knocking out the 'Iron Hands of Siam' via a vicious head kick after just 30 seconds. Due to his results on the local scene – including winning the U.M.C. Contender title against Imed Boukouayel - Sergio would become involved with the It's Showtime
organization, making his debut in Milan
and defeating local fighter Matteo Lippi by knockout.
Towards the end of 2010, Sergio was called up to face Frenchman Mikael Peynaud for the first ever It's Showtime 61MAX world title. The fight had some controversy as the match was stopped in the second round after a clash of heads left Peynaud with a cut. Unable to continue, the fight went to the judge's scorecard, resulting in a technical decision victory for the Surinamese fighter in his home town of Amsterdam
. In December of that year, Sergio was back in action, defending his world title after two months against Japanese K-1
fighter Masahiro Yamamoto in Athens
. This title fight was much more clear cut than the first with Sergio winning by TKO in what was a commanding performance. In March 2011, Sergio defended his It's Showtime world title once again but was unable to retain his crown, losing by majority decision
after five rounds to Karim Bennoui at the event in Brussels
