ONE Championship Muay Thai fights at Lumpinee Stadium on June 12

At Lumpinee Stadium in Bangkok, ONE Championship staged two Muay Thai bouts on June 12. The main event of ONE Friday Fights 158 featured Thai slugger Maisangkum Sor Yingcharoenkarnchang against Petnamkhong Sor Maneekhot in a strawweight showdown. Maisangkum, coming off a unanimous‑decision win and a prior first‑round knockout loss, said he will start cautiously and increase pressure after the first round, aiming to finish with his signature left‑hook to the body.

Earlier on the same card, The Inner Circle 18 presented veteran Sornsueknoi FA Group against Rambong Sor Therapat in a fly‑weight contest. Sornsueknoi outlined a plan to grind and pressure his opponent, using short hooks, elbows and knees, and emphasized improved footwork after a recent TKO win. Both fighters are seeking victories that could move them closer to six‑figure contracts with ONE Championship.
