The bout, Viloria's first in Macau since his loss to Juan Francisco Estrada, was expected to be an easy win for the "Hawaiian Punch" who was the naturally bigger man, though a few had tipped Zuniga to be a potential banana skin for for the former champion who had been described by some insiders as "shop worn".
In the opening round the action was tight with Viloria probably just taking it, though few would have complained had it been scored even. The second was similar with both men making a claim to take the round with their own notable successes. Likewise round 3 was close with Zuniga using clever movement to frustrate Viloria though later in the round Viloria finally managed to pin down Zuniga as the two began to exchange heavy shots, for the vast part of the exchanges however Zuniga more than held his own.
After 3 rounds it was certainly close and it appeared that those who had described Zuniga as a banana skin though in round 4 Viloria finally begin showing his class as he banged a series of hard shots on the head of Zuniga who was forced to rely on his toughness for a few moments before fighting back. It was that series of hard shots that gave Viloria the round and started a turn around for Viloria.
Having began to show his class in round 4 Viloria managed to show world class ability in round 5 as he landed a devastating body shot that sent Zuniga down for the count. It wasn't as physically impress as the body shot KO scored by Tomoki Kameda a week ago but it was equally as effective in ending a fight that had been competitive prior to the stoppage.
With the win Viloria will have shaken the demons of his loss to Estrada and may well be looking for a return to the world level later this year, however with the Flyweight division being packed with talent he may need to wait a while for an opportunity to return to the top. For Zuniga this was a good showing, prior to being stopped, and we honestly hope we get to see him in action with another notable name sooner rather than later.
