LAS VEGAS — Brian Viloria was staring at the canvas while Omar Nino was pumping his fist during a post-fight celebration.

Judging by that scene one might have thought that Nino, of Guadalajara, Mexico, had beaten Waipahu's Viloria in a World Boxing Council light-flyweight bout at the Thomas & Mack Center last night.

In fact, neither won the 12-round bout. But despite being knocked down twice, the 107-pound Nino, 30, retained a title he had won in his previous fight against the 108-pound Viloria, 25, by escaping with a majority draw in the rematch.

"I don't know what more I have to do," Viloria told espn.com. "I knocked him down twice. I clearly won the fight. I don't understand this."

Viloria (19-1-1, 12 KOs) and Nino (24-2-2, 10 KOs) tied 113-113 on the scorecards of judges Dave Moretti and Carole Castellano while Nino was scored a 115-112 winner on Samuel Conde's card.

Nino won the final two rounds, 10-9, on all three judges' cards. Nino not only was more active in both of those rounds, but he finished the 12th with a multiple-punch flurry that left Viloria dazed.

That finish not only was a positive endorsement for Nino, but it took its toll on Viloria, who was taken to an unspecified area hospital by ambulance immediately afterward, according to a Top Rank Boxing official.

The reason for Viloria's trip to the hospital could not be verified, but he suffered a cut on his eyebrow in the 10th round. During that round, Viloria caused a sizable cut on Nino's nose and won it on two judges' scorecards.

After the 10th round, though, Viloria seemed to run out of steam while Nino threw the majority of the punches.

For the bout, Viloria threw 599 punches compared to 587 for Nino, but Nino connected on 148 while Viloria connected on 123.

The most telling statistics were in Viloria's favor, as he threw 376 power punches compared to 339 for Nino and knocked Nino down in the fifth and ninth rounds. The first knockdown required a standing eight-count while the second occurred just before the bell. The knockdown rounds were the only two that Viloria won on all three judges' scorecards.

But even in the ninth round, Nino was more active until Viloria floored him.

Viloria was the more active fighter during the majority of the first seven rounds, but a Nino uppercut that closed the seventh round stunned Viloria and took away his aggressiveness for the rest of the fight.
