Deontay Wilder is the undefeated WBC heavyweight champion. In Brooklyn, New York, the 30-year-old American defeated Artur Szpilka from Poland by knockout in the ninth round and then loudly challenged Tyson Fury, who had conquered Klitschko, to the ultimate duel. “You’re just a swindler,” Wilder yelled. “I’ll hit you anytime, anywhere, even in your own backyard if you want.”
