The strawweight brought the crowd to its feet with a takedown off a Vy Srey kick, and immediately rained punches down from side mount.

Vy Srey punched back, but was not able to mount any type of escape from the position as Osman battered her with punches, elbows, and knees.

With 30 seconds left in the round, Osman transitioned to the full mount, posted with her right hand on her opponent, and thundered punishment onto the Cambodian’s face until the referee finally stopped the contest.

The end came at 4:58 of the first round.

“I knew she was going to throw a kick and I was going to throw her to the ground and that’s what I did,” said Osman in her post-fight interview in the cage.

Osman’s record improves to 5-3 with the victory. Vy Srey suffers her first professional MMA defeat, and her young career mark dips to 2-1.
