Irish boxer Adam Nolan advanced to the second round of the welterweight division at ExCel tonight.

The rangy Enniscorthy fighter expertly utilised a massive height and reach advantage against Ecuador’s Carlos Sanchez Estachio to record a comfortable 14-8 success.

The Irish southpaw looked polished from the bell and frustrated his muscular opponent throughout the contest.

The Bray BC pugilist built up a 6-3 lead at the end of the first round and extended his advantage to 11-6 at the end of the second.

Nolan’s ability to shift at will from his customary southpaw stance to an orthodox attack caused Sanchez Estachio a major headache.

However, the Ecuadorian upped his game in the closing stages.

He unleashed a flurry of potent upper cuts and appeared to shade the final round, but the judges scored the round 3-2 as Nolan progressed with something to spare.

Nolan admitted after the victory: "I was a little over-eager to get in there and get the win. It's like a cauldron and I was a little taken aback at the start, but without the crowd I wouldn't have got through it.

"I made it hard for myself but the main thing is I got through. My performances to get here were top-class and there will be pressure on the Russian. I will go out there and throw off the shackles and try to box with a free spirit."

Nolan was the third Irish winner after Saturday's victories for John Joe Nevin and Darren O'Neill and he added: "We have all sorts in the team and we're bonding really well. We are all behind each other 100%."

Four years ago Alexis Vastine had left the Olympic ring in a fury after two controversial final-round penalties cost him victory against the Dominican Republic's Felix Diaz and forced him to settle for a bronze medal.

Today the 25-year-old Frenchman enjoyed a happier return to the Games as he won his first-round bout in the welterweight division 16-12 against Germany's Patrick Wojcicki, and said his Beijing disappointment was in the past.

Vastine said: "It was a bad memory for me but you can't stay in the past, you've got to look forward. I want to look forward and to go further than I did four years ago."

Vastine's experience told against the 20-year-old German as he crafted a two-point advantage at the end of the first round and stayed in control with a powerful, accurate display which marks him down as one of the favourites at 69kg.

Also at welterweight, there were wins for Mongolia's Tuvshinbat Byamba, Canadian Custio Clayton and Australia's world number five Cameron Hammond, who had too much for Nigeria's Abdoulaye Hima, winning 13-6.

In the lightweight division, Kazakhstan's fifth seed and world bronze medallist Gani Zhailauov was lucky to survive against Thailand's Saylom Ardee, coming from behind to pull out victory on countback after a 12-12 draw.

Puerto Rico's Panamerican youth champion Felix Verdejo Sanchez, age 19, beat Juan Huertas Garcia of Panama 11-5 with a patient display of counter-punching, while Liu Qiang of China had too much for Australian Luke Jackson, coasting to a 20-7 success.
