As long as WC World Minimumweight Champion Chayaphon Moonsri stays unbeaten Floyd “Money” Mayweather will still keep fighting, even if they are amateurs like in his last “fight!”

Moonsri is from Bangkok, Thailand, and yesterday he knocked out Panama’s Leroy “El Sencacional” Estrada, 16-3 (6), in the fifth round in the outdoor arena at Nakhon Ratchasima in Thailand. US Referee Jay Nady worked the bout. Estrada was down twice in the third round, twice in the fourth round and for the fifth time in the fifth round.

This was Moonsri’s ninth title defense since winning the title November 6, 2014, stopping Mexico’s Oswaldo “El Gallito” Novoa, in the ninth round. All of Moonsri’s 50 fights have been in his home country of Thailand.

The 32 year-old Moonsri made his debut on January 26, 2007, and has been active since winning the vacant WBC Youth World Minimumweight title in his third fight and defending it eight times. In December of 2009 he won the interim WBC International Minimumweight title defending it twice.

The WBA World Minimumweight champion Thammanoon Niyomtrong, 17-0 (7), is also from Thailand in the city of Surin. He won that title in January of 2016. It would only make sense for he and Moonsri to unify but evidently if hasn’t happened yet.

The other two world champions are both from Japan. Hiroto Kyoguchi, 9-0 (7), holds the IBF title and Ryuya Yamanaka, 16-2 (5), holds the WBO title. They should unify and fight the winners from Thailand but in this day of multi titles it is not the usual to unify. Look to Mayweather 51st fight coming to your nearest PPV venue against “another” unbeaten 0-0 opponent!
