Jesse “Bam“ Rodriguez is keeping his title…

“This is the youngest champ in boxing and he already might be a pound-for-pound great,” said Rodriguez’s promoter, Eddie Hearn. “He’s here for legacy; he’s here to be remembered.”

It was a dazzling display from Rodriguez, who headlined in his hometown for the first time. He used an excellent southpaw jab, beautiful footwork and plenty of angles to keep Rungvisai off-rhythm and at the end of his power shots.

Rungvisai (50-6-1, 43 KOs) owns victories over a pair of future Hall of Famers in their primes — Roman “Chocolatito” Gonzalez and Juan Francisco Estrada — so it was particularly impressive the way Rodriguez was able to pick off his heavy shots and win every round in dominant fashion.

The plodding 35-year-old from Thailand needs to set his feet to deliver his power shots, but Rodriguez never allowed him to do so. He presented a moving target, and on the rare occasion Rungvisai did close distance, “Bam” turned him around.

“In the third round I felt his power wasn’t the same,” said Rodriguez, who entered the fight rated No. 5 by ESPN at 115 pounds. ” … That’s when I decided to take over. … Having Robert Garcia in my corner is a huge advantage.”

Rodriguez, whose brother Joshua Franco holds a secondary title at 115 pounds, said he could campaign at 112 pounds before returning to the weight class.

“He’s a very underrated fighter and it’s a matter of time until he gets his shot,” Rodriguez said of Franco, who is ESPN’s No. 6 junior bantamweight.

Rungvisai, ESPN’s No. 3 boxer at 115 pounds, lost for just the second time since a 2014 technical decision defeat to Carlos Cuadras. And it was Cuadras whom Rodriguez defeated in February to announce his arrival and pick up his first world title, though Estrada remains the WBC’s franchise champion in the weight class.
