According to the camp of Mexico's Marco Antonio Rubio (56-6-1, 49KOs), he will receive the WBO's number one ranking, at middleweight, when the organization's new ratings are released. The move to place Rubio at number one has caused a minor stir because the boxer has staged his last two fights above the middleweight limit.
In February, he challenged Julio Cesar Chavez Jr. for the WBC middleweight crown and lost a twelve round decision. He returned to the ring three more times in 2012 and won all three fights by knockout.
At the moment the WBO champion is undefeated Peter Quillin (28-0, 20KOs). He defends the title against Fernando Guerrero (25-1, 19KOs) on February 9th at Barclays Center in Brooklyn, New York.
