Puerto Rico's Jantony Ortiz Marcano was one of a number of boxers to light up the ring on an exciting night of action at the ExCeL.
Ortiz Marcano is eager to continue his island's fine Boxing tradition after moving into the last 16 of the light flyweight category with a 20-6 win over Ghana's Tetteh Sulemanu.
Steeped in the stories of fighters like the great Felix Trinidad and two-weight world champion Daniel Santos, the last Puerto Rican boxer to win an Olympic medal in 1996, the nation's young team is targeting further glory.
Ortiz Marcano, who celebrated his 18th birthday last week, is one of four teenagers in the five-man Puerto Rican squad. The team's fifth member, middleweight Enrique Collazo, has already been knocked out of the tournament.
He certainly relished his Olympic debut, arriving in the ring with a huge smile on his face and proceeding to showcase a series of flashy moves as he took apart his opponent, establishing an 8-1 lead within three minutes.
Ortiz Marcano said: 'I was smiling going into the ring and coming out of the ring because that is how I feel and I don't want to change anything. I told my corner they had to keep smiling too. I fought well and I have a lot more to come.'
