HyunSung Park

Overview

Three UFC wins, three finishes, and the only two men who beat him both did it by submission.

HyunSung Park, nicknamed "Peace of Mind," is a South Korean flyweight out of Tiger Muay Thai in Phuket, Thailand. His UFC record is 3-2, inside a 10-2 professional record across all promotions. He debuted on June 9, 2022, and carries a two-fight losing streak into his next bout.

He finishes fights and he gets finished. Nothing in his UFC run has gone to the scorecards.

UFC Career

Park's two Road to UFC fights came first, and they aren't part of his UFC record. He stopped Jeremia Siregar in round 1 (3:56) at Road to UFC 1.4, then submitted Top Noi Kiwram in round 1 (3:05) at Road to UFC 1.6.

The UFC run began in February 2023 with a third-round submission of SeungGuk Choi. He followed with a second-round TKO of Shannon Ross in December 2023 (3:59). In May 2025 he submitted Carlos Hernandez in round 1 at 2:26, his fastest UFC win and his only first-round finish in the UFC. That made three straight UFC wins.

Then the main event. In August 2025 Park headlined against Tatsuro Taira, an opponent our model rates as strong, and was submitted in round 2 at 1:06. Two months later, Bruno Silva submitted him in round 3 at 2:15.

Three wins, then two losses. Both defeats came on the mat.

Fighting Style

Park is a grappler first. He hunts for submissions more than almost anyone on the UFC roster, and two of his three UFC wins ended that way, one in the first round and one in the third. The other came by TKO in the second.

On the feet, he lands at a rate close to the UFC average and defends about as well as most. He takes fewer strikes than the typical fighter, though his accuracy is below par.

The weak spot is stopping takedowns. He gets taken down more than most, and both of his UFC losses ended in submissions. That makes his fights a back-and-forth on the mat, where he is dangerous but also exposed.
