NEW YORK — Deontay Wilder believes they are coming, the mega matchup with Anthony Joshua and the rematch with Tyson Fury. Until then, he moved onto some business with Dominic Breazeale. He took care of it quickly and emphatically. Wilder got back into the win column Saturday night, knocking out Breazeale with an overpowering right hand in the first round to defend his heavyweight title. “There’s been a lot of animosity and a lot of words that were said and it just came out of me tonight,” Wilder said. Wilder hurt Breazeale with a right to the head early in their fight at Barclays Center, but the challenger had recovered from that early onslaught.
