Oscar Collazo remained undefeated and won the WBO International flyweight title on Saturday night with a devastating two-round victory over Neider Valdez.

The unified WBA, WBO and Ring Magazine minimumweight champion improved to 15-0 with 12 knockouts after defeating Valdez three times before Mexico’s corner stopped the fight at 2:35 of the second round.

Making his final appearance at 112 pounds, Collazo showed his strength immediately transferred to the upper division, defeating Valdez from the opening bell at Frontwave Arena in Oceanside, California.

The Puerto Rican striker repeatedly found a home for his left hand and left no doubt about the outcome before the fight was called off.

“I felt great at 112 pounds. I love this division. In fact, I want to stay here for a long time,” Collazo said.

Knockdowns

Collazo admitted that he had already called for the fight to be stopped.

“After the third knockdown I was basically saying, ‘Never again, never again’. It was the right decision for his safety. His corner was well checked.

The victory added another belt to Collazo’s collection and enhanced his growing reputation as one of boxing’s most invigorating champions in the lower weight division.

Looking ahead, Collazo has made it clear who he wants next.

“The fight with Ricardo Sandoval definitely interests me. I really want that fight. I’m ready for gigantic fights. I’m ready to make history. That’s the fight I want next.”

Sandoval currently holds the WBA flyweight title, making this one of the most attractive fights available if Collazo continues his climb in weight.

The event was broadcast live on DAZN and was promoted by Golden Boy Promotions in partnership with Miguel Cotto Promotions.

Dave Allen returned to winning ways on Saturday night, going the full distance in less than six weeks after a controversial stoppage defeat to Filip Hrgovic.

The popular heavyweight outpointed Ross McGuigan over four rounds in Rotherham, improving his record to 26-9-2.

Allen featured just 36 days after his defeat to Hrgovic at Doncaster. This fight sparked debate when his corner threw in the towel after three rounds.

The quick comeback only deepened that debate, with Allen previously noting that he was never knocked down despite sharing the ring with some of boxing’s greatest hitters.

Against McGuigan, Allen managed to gain valuable runs under his belt and shake off the disappointment of defeat to Hrgovic without suffering significant penalties.

McGuigan, from Peckham, London, lost ten times in eighteen fights before Allen’s tally was eleven. The 40-year-old was stopped by the debutant in his previous appearance in May.

The four-round contest was a modest return for the “White Rhino,” but one that allowed him to stay lively ahead of his next scheduled appearance on July 25.

The trip also served as a reminder that Allen has no intention of remaining passive despite the setback, with another fight already on the calendar this summer.

After Hrgovic’s defeat, Saturday’s victory gave him a chance to rebuild the momentum and gain some rounds before taking on the next challenge.

Allen’s next fight is expected to be another stepping stone before he pursues greater opportunities later in the year.
