Despite competing in over 400 fights throughout his illustrious career, Prajanchai PK Saenchai admits there's only one fighter who pushed him to the limit.That distinction belongs to interim ONE strawweight kickboxing world champion Jonathan Di Bella.The reigning ONE strawweight Muay Thai world champion achieved two-sport glory at ONE Friday Fights 68 last year when he outclassed his Italian-Canadian rival via unanimous decision for the vacant 125-pound kickboxing throne.Prajanchai knew he was in for a tough battle, considering the Italian-Canadian owned an unblemished 12-0 professional record entering the high-stakes contest.Sure enough, Di Bella utilized his reach advantage and boxing combinations to create early problems for the Thai veteran.The two-sport kingpin recalled in a ONE Championship interview:"In the first fight with Jonathan Di Bella, in rounds one and two, I couldn't figure out his style yet. By the third round, I started to get a read on him, and the fight became easier because I knew what his dangerous weapons were."
