Jessica Andrade wins strawweight title with Rose Namajunas at UFC 237, winners results.

After losing the first round of the UFC 237 main event handily, Jessica Andrade knew she had to mix things up.

Defending UFC strawweight champion Rose Namajunas dominated the first five minutes of the bout, using her speed and range to fluster her Brazilian foe. But then Andrade decided to make it a firefight in the second round, and she capped her performance with one of the most stunning finishes in recent memory.

Andrade (20-6 MMA, 11-4 UFC) slammed Namajunas (8-4 MMA, 6-3 UFC) for the knockout, winning the championship at the 2:34 mark. The strawweight title fight was the UFC 237 main event from Jeunesse Arena in Rio de Janeiro and streamed on ESPN+ pay-per-view.

Namajunas, who entered the fight on a 13-month layoff due to injury following a pair of exciting title wins over Joanna Jedrzejczyk (who defeated Andrade in 2017), put forth a blistering first round that acted like a highlight reel of her incredible evolution as a striker.

Andrade, 26, a former bantamweight who has reinvented herself as a knockout puncher at 115 pounds, was willing to take the damage throughout in order to get close enough and twice got her hands on Namajunas in the opening round for slam attempts that were thwarted by the champion securing Kimura attempts while in midair to minimize the impact of the landing.

"I was very certain in what I had to do in that second round," Andrade said. "I never threw that move, I never piledrived anyone in the UFC. That's my nickname and I wanted to do that. I knew she was slowing down."

"I'm very happy but this is really his belt," an emotional Andrade said as she handed the belt to her coach, Gillard Parana. "If he hadn't put the gym together 10 years ago, I wouldn't be here."
