According to the World Boxing Council, WBC super flyweight champion Srisaket Sor Rungvisai has requested a voluntary defense before meeting his mandatory obligation with Juan Francisco Estrada.

In March of this year, Sor Rungvisai (44-4-1, 40 KOs) shocked the world when he won a twelve round unanimous decision over heavily favored Roman 'Chocolatito' Gonzalez to capture the WBC title at New York's Madison Square Garden.

The winner of that contest was initially ordered to fight Carlos Cuadras. But that didn't happen. Because there controversy with the scorecards, and an appealr was filed by members of Gonzalez's team, the WBC would instead order a rematch between Gonzalez and Sor Rungvisia. They also ordered a final eliminator, for the WBC interim-title, between Estrada and Cuadras.

The doubleheader was finalized and took place last month before a sell-out crowd at the StubHub Center in Carson, California.

In the main event, Sor Rungvisai set the record straight with an unexpected destruction of Gonzalez, who was knocked out cold in the fourth round.

Also on the card, Estrada (36-2, 25 KOs) won a close, twelve round decision over Cuadras to secure the world title shot at Sor Rungvisia.

The fight between Estrada and Sor Rungvisia was being targeted for early next year, as part of another planned HBO card featuring fighters from the super flyweight division.

Even before the Gonzalez rematch was ordered, Sor Rungvisai was already attempting to make a voluntary but his request was denied. This time around, he is likely to get his way. The boxer, who is now a national hero back home, would like to make at least one defense of his title in Thailand.

As with anything else, Sor Rungvisia could use the voluntary as leverage to make a bigger payday with Estrada - of the offer is increased to ensure that bout happens sooner than later.
