Brilliant Cuban light flyweight Joahnys Argilagos underlined his rich potential as he became the first boxer at the Rio Olympics into the semi-finals to guarantee at least a bronze medal.
The 19-year-old Cuban prodigy and world champion had Kenya's Peter Warui running around in circles on the way to a unanimous points decision.
Argilagos displayed the full array of his electric footwork, at one point ducking a haymaker from Warui, whose momentum took him tumbling into the ropes.
The Cuban merely grinned back at his opponent and later delivered a sucker-punch while appearing to look in the opposite direction.
Argilagos faces Colombian Yurberjen Martinez -- who he has trained with in the past -- in the semis on Friday, after he defeated Samuel Carmona Heredia of Spain on a split points decision.
"I felt more confident that in my first fight," said Argilagos, after delivering one of the most impressive boxing displays in Rio to date.
"I knew I was going to bring joy to Cuba and I stuck to my tactical masterplan."
"The Colombian is going to be a very tough rival," added Argilagos, also a former youth world champion and one of the hottest prospects around.
"We have never fought but we have trained together and I know that he has some good weapons."
