Heading into UFC 237, all four of Irene Aldana’s UFC fights, win or lose, had gone the distance.

And it seemed things were heading that way once again during Aldana’s bout against Bethe Correia on Saturday night.

In the latter half of the final round, however, Correia made an ill-advised attempt for the fight’s first takedown. When she failed, Aldana (10-4 MMA, 3-2 UFC) took her back and swiftly transitioned into an armbar.

Correia (10-3-1 MMA, 4-3-1 UFC) tapped, and not only did Aldana earn her first stoppage victory in the UFC, she also earned her first career submission win. The time of the stoppage was 3:24 of the third round.

“I’m more known for my boxing and my striking,” Aldana said. “And I’m glad I could show my jiu-jitsu here … I’m glad I got the victory by armbar.”

The bulk of the fight was a simple tale: Aldana did her best to use her length advantage to keep Correia at bay; Correia did her best when she closed the distance and ate a shot or two to land two or three.

Correia seemed to be doing the better job of this in the third round before she made her fight-ending mistake.

Dating back to her famous loss to Ronda Rousey at UFC 190, Correia is now on a 1-4-1 skid. Aldana has won three in a row after dropping her first two UFC fights.

The women’s bout was scheduled to be held at bantamweight, but was changed to catchweight after Correia weighed in at 141 pounds Friday. The fight opened the UFC 237 main card from Jeunesse Arena in Rio de Janeiro and streamed on ESPN+ pay-per-view.
