Top Rank's CEO Bob Arum believes that his company has found a new superstar in Nicholas Walters, who stunned over 9,000 fans at the StubHub Center in Carson with his sixth round knockout of Nonito Donaire, who a few years ago was widely regarded as one of the best pound-for-pound boxers in the sport.

Walters (25-0, 21 KOs) dropped Donaire (33-3) in the third round and then put him away with a second remaining in the sixth, when he landed a big overhand right.

"I've never seen a featherweight with as much power as Walters. Nothing like the concussive power this kid has," Arum said.

Walters was very humble after the victory, because Donaire could have went in another direction.

"We worked hard for this victory. Donaire is a super great champion. I know I have to respect him, and that's what I did. He caught me with a few shots," Walters said.
