The five-time four division world champion Amanda Serrano (31-1-1, 23 KO) of Puerto Rico is 4 pounds away from her historic scheduled fight for Saturday, April 22, at the Barclays Center in Brooklyn, New York.

She will face former world champion Dahiana Santana (35-8, 14 KO's) of the Dominican Republic in a duel that will have the vacant 118-pound world championship of the World Boxing Organization.

"I'm happy because I'm weighing 122 pounds and I understand that I will not have any problems in making 118 pounds at the weigh-in on Friday," said Amanda Serrano, who in her last performance beat two-time world champion Yazmin ' La Rusita' Rivas of Mexico.

In winning the fight, Serrano would become the first five division world champion from Puerto Rico. Since 2012, Miguel Cotto was the only boxer from Puerto Rico to win world titles in four weight divisions - junior welterweight, welterweight, junior middleweight and middleweight - until Serrano tied him.

Serrano has now won titles at super featherweight, featherweight, lightweight and super bantamweight.

"On Saturday, more history will be written in women's and Puerto Rican boxing, when I become a five-division world champion, an accomplishment that has never been achieved in women's boxing and Puerto Rican boxing," Serrano said.

Amanda's coach, Jordan Maldonado said, "Before, they told us that we were crazy because at first Amanda only fought between 126 and 130 pounds, but since then she has been world champion in those weights and also at 135 and 122 pounds. Amanda is small, but when she enters the ring everything changes because we work for that."

The Serrano-Santana duel will be broadcast live on Showtime Extreme. The main event of that show will be a WBC welterweight final eliminator between former world champions Shawn Porter and Andre Berto.

At present, Amanda and her older sister, Cindy Serrano, are the only world champions from Puerto Rico.
