Two-division KSW champion Mateusz Gamrot retained his lightweight title and extended his unbeaten record with a strong performance against short-notice replacement Marian Ziolkowski at KSW 54 on Saturday night. Lightweight and feathweight champ Gamrot (17-0) outmuscled Ziolkowski (21-8-1) throughout the five-round title fight in Warsaw, Poland to maintain his status as KSW’s resident “champ champ” as he dominated the action to earn scores of 50-45, 50-45, 49-46 from the three cageside judges. The co-main event saw former boxing contender Izu Ugonoh (1-0) make a successful start to his MMA career as the Pole earned a first-round TKO victory due to a leg injury to his opponent Quentin Domingos (5-2) in their heavyweight matchup.
