Nakhon Ratchasima, Thailand - WBC minimumweight world champion Wanheng Menayothin (50-0, 18 KOs) entered the fight with two loaded guns - as he matched the undefeated record of Floyd Mayweather - with a fifth round knockout of mandatory challenger Leroy Estrada (16-3, 6 KOs) - who went down five times in the contest.
The Thai champion was landing the bigger punches from the start of the contest. In the third round, Menayothin dropped Estrada. And then a moment later he dropped him for a second time in the round. Once Estrada got, up Menayothin was battering him with punches and nearly stopped him. Estrada showed guts in trying to fight off the attack.
In the fourth round, Menayothin dropped Estrada very hard for the third time in the fight. And then a barrage of punches sent Estrada down for a fourth time at the bell, which likely saved him from a knockout loss at that point - although the end was near.
Menayothin continued to punish him in the fifth round, scoring a fifth knockdown - and referee Jay Nady had seen enough and waved off the fight to save Estrada from any further punishment.
Estrada, who was riding a four fight win streak, was coming off a win over former world champion Saul Juarez from last May.
Most of the hype around this contest, was Menayothin matching Mayweather's record.
Even World Boxing Council President Mauricio Sulaiman flew out to the contest to watch it from ringside.
Mayweather retired from the sport of boxing in August of 2017, after scoring a tenth round stoppage over UFC superstar Conor McGregor at T-Mobile Arena in Las Vegas.
The victory over McGregor allowed Mayweather, who is a former five division world champion, to break the 49-0 record of heavyweight legend Rocky Marciano.
At 40 years-old, Mayweather walked away from the sport with a perfect record of 50-0, with 27 knockouts.
Of course Mayweather's record is a universe above the competition that Menayothin has faced at 105-pounds.
