Watch it: Srisaket Sor Rungvisai's beat down in Thailand

Srisaket Sor Rungvisai knocked out overmatched Kwanthai Sithmorseng after three rounds on Friday in Thailand, the home country of both fighters.

Sor Rungvisai, a former two-time 115-pound titleholder, battered the former strawweight champ from the opening bell until the loser could no longer continue.

Sor Rungvisai (50-5-1, 43 KOs) is now in position to face the winner of tonight’s (Saturday) title-unification bout between Juan Francisco Estrada and Roman Gonzalez in Dallas.

Here are the highlights of Sor Rungvisai’s dominating performance.
