#3. Rodtang Jitmuangnon's Muay Thai wars against Jonathan Haggerty
If one looks at the way Rodtang fights, they would assume his opponents stole his lunch money.
The famed Muay Thai wrecking ball is intensity personified. It raised some eyebrows when then-champion Johnathan 'The General' Haggerty, after winning the belt, called out Rodtang as his next opponent. People thought it was bold for him to call out such a dangerous ONE Championship fighter.
In hindsight, the matchup was perfect. A tall, lanky technician with his clinical precision versus a short stocky brawler with his aggression and pressure. The first fight had a pace that can cause a heart attack just by watching it. The two threw everything they had at one another. Rodtang took the tightly contested fight via unanimous decision.
In the rematch, Rodtang did what he does best: pressure, pressure, pressure. Rodtang stalked Haggerty all throughout, while eating everything 'The General' threw at him. The ONE Championship king closed the show in the third round, knocking down Haggerty three times to earn the TKO victory.
Though the rivalry is at 2-0, both fighters are still in their early 20's and arguably still reaching their athletic prime. Fans might see these two go to war again in the ONE Championship Circle in the near future.
