Vasyl Lomachenko was described as "superhuman" by his promoter Bob Arum after his dominant win over Guillermo Rigondeaux, but the Ukrainian insisted it was not a big success for him.
Lomachenko prevailed in New York in the sixth round after Cuban Rigondeaux retired in the sixth round with a hand injury, suffering his first defeat as a professional having been on a wrong end of a one-sided contest.
The victory marked Lomachenko's ninth straight win and the fourth successive bout in which he has forced his opponent to retire.
And Arum said of Lomachenko: "This guy is superhuman.
"Rigondeaux is not a ham-and-egger. Nobody came close to beating him. But with Lomachenko, he had nothing. He was totally bewildered.
"He goes to the ground [to cover] and Lomachenko is there waiting [to hit him] on the other side."

Rigondeaux was unbeaten in 17 fights at super bantamweight level, but the move up two levels to super featherweight proved a step too far as Lomachenko once again proved his pedigree in the first world title fight to feature a pair of two-time Olympic gold medallists.
But Lomachenko - who afterwards suggested he should change his name to "No-mas-chenko" played down his triumph, saying: "He's [Rigondeaux] a tough fighter, a king in boxing, but a king in his weight class.
"It's not a big win for me because of that."
Cuban Rigondeaux added of Lomachenko: "He's a very technical, quick, explosive fighter. He is an excellent boxer."
