Park (10-1 MMA, 3-1 UFC) stepped up on just a few days' notice after Taira's original opponent, Amir Albazi, withdrew due to injury. The opponent switch was no problem, as Taira ended the fight 1:06 into Round 2 by submission.

The Japanese rising star defeated short-notice opponent Hyun Sung Park with a second-round submission via face crank at the UFC APEX in Las Vegas, bouncing back in dominant fashion after a split-decision loss against Brandon Royval this past December.

Tatsuro Taira put his first loss far back in the rear-view mirror. The 25-year-old Japanese flyweight made quick work of Hyun Sung Park in Saturday’s UFC Vegas 108 main event, needing a little more than a round to lock in a face crank and force a tap from the short-notice replacement.
