Michael Conlan wants a rematch with Russian rival Vladimir Nikitin - the man who controversially defeated him at the Rio Games - after a classy victory in New York last night.
Conlan made it 11-0 in the paid ranks against Mexican Ruben Garcia Hernandez, scoring 100-90 verdicts by all three judges.
The Northern Ireland boxer, 27, was given a 100-90 verdict by all three judges in the 10-rounder and afterwards called out Nikitin, who had earlier appeared on the Madison Square Garden card when earning a split-decision victory over Juan Tapia of the USA.
"Vladimir, I know you're here tonight and we need to do it again," said Conlan.
"We need to have that rematch. I need to right a wrong that shouldn't have been written."
It was a chastening night for Paddy Barnes, who said he is likely to retire after a hugely disappointing defeat to Oscar Mojica.
The 31-year-old Belfast man won bronze medals at the 2008 and 2012 Olympics and was Ireland flag bearer at the Rio Games in 2016.
Having turned pro after that Olympics in Brazil, Barnes suffered a knockout defeat to Cristofer Rosales in his bid to become the WBC flyweight champion of the world at Windsor Park last summer.
He moved up two weight divisions from flyweight to bantamweight for last night's bout with American Mojica but was still expected to come through his St Patrick's Day test.

Instead, he came out the wrong side of a 58-56, 58-56, 56-58 split decision scorecard, and afterwards gave an extremely honest assessment of his performance and future prospects.
"In the first round, he broke my nose. To be honest, I don’t know how the judges scored it close because I thought he won every round. I’m too small for bantamweight, but to be honest with you, I’ll probably retire now.
"Is there any real point in boxing on after a fight like that?
"The fans are great but at the end of the day it’s my health and all. If I’m going to box like that, what’s the point in boxing anymore?
"I strongly think this is it. I always thought if I lost again, I’d retire. The fight wasn’t even close. I thought he won every round."
