Amanda Serrano once again proved why she is one of the best female fighters, pound-for-pound, in the sport.

The Puerto Rican fighter improved her record to 33-1-1 and 25 KO's, while retaining the World Boxing Organization (WBO) junior featherweight belt with a third round knockout of Hungarian Edina Kiss in the headline bout of a Puerto Rico Best Boxing card from the San Juan Ballroom of the Sheraton in Puerto Rico.

"She came to fight," Serrano said to José Bartolomei. "And I don't dislike her, because if it wasn't for her, I would not be fighting tonight [Kiss came in as a late replacement]."

The referee stopped the match one minute into the third round due to the heavy punishment Kiss (13-5, 5 KO's) was receiving from Serrano. The Puerto Rican had convincingly won the other two rounds.

"I do not know what to do now, I have to go back to the gym, I have to see if I'm going to look for a sixth title. No matter what, the best fighters are between 122 and 130 pounds, but nobody wants to fight me," Serrano said.

Also on the card, Jeyvier Cintron got a win by knocking out Guillermo Dejas (7-8-1, 2 KOs) in the second round. With the win, Cintron improved his record to 2-0 and 1 KO.

"I took it easy.When I hit him hard in the second round, that's where he slowed down," Cintron said after his hard-fought victory. "He was using his head, his hand, he is a veteran boxer, but then I could keep him at a distance with the jab, and when I had to be aggressive, I was."

Jonathan 'Polvo' Oquendo (27-6, 17 KO's) defeated Nicaraguan Orlando Rizzo (19-11, 11 KO's) by knockout. Oquendo had been inactive for 19 months. Rizzo's corner prevented the Nicaraguan from leaving for the sixth round after a bad cut was suffered below the left eye.

Meanwhile, Brazilian Olympic gold medalist Robson Conceicao (4-0, 3 KO's) blew away Bernardo Gomez (17-8, 11 KO's) in the first round with a powerful combination.  The series of punches left the Gomez on the ground for several minutes in a fight that was stipulated for eight rounds at 133 pounds.
