Turning Stone Casino, Verona, New York - Rising star Jaime Munguia crushed Sadam Ali to take the WBO junior middleweight title with a fourth-round stoppage.

Munguia, who had a substantial size and punching power advantage, easily won the lopsided bout. The 21-year-old Mexican floored Ali twice in the opening round, once in the second and again in the fourth before the referee put a halt to the slaughter.

Ali indicates that he caught early in the first round, that he never fully recovered from for the rest of the contest.

"He [Munguia] caught me early," said Ali. "That's what affected me. I don't want to give any excuses. He was the better man tonight. I have to check with my team to see a what's next for me."

In the co-feature, Mexico's Rey Vargas retained his World Boxing Council title with a unanimous decision over Azat Hovhannisyan in a bloody showdown between a pair of super bantamweight fighters.

Vargas made his third straight successful defense of the title despite finishing the 12-round fight with blood streaming down both sides of his face, the result of headbutts in the eighth and 12th rounds.

Vargas, who is now a perfect 32-0 in his career, won on all three judges' scorecards including one who had it 118-110. The other two scored it 117-111 and 116-112.

He fought the final four rounds with blood flowing freely but the cuts above his eyes did not seem to affect his vision that much.

Vargas was coming off a twelve-round unanimous decision over undefeated Oscar Negrete in December. Hovhannisyan, who is trained by the legendary cornerman Freddie Roach, dropped to a record of 14-3. He was fighting for his first world title and the loss ended his eight-fight win streak.
