Having already accomplished so much in the world of Brazilian jiu-jitsu, Bia Mesquita now is set on dominating the MMA world in the same way she dominated Irina Alekseeva in her Octagon debut during the UFC Rio preliminary card.

After about a minute of feeling out, Alekseeva clipped Mesquita with a punch. But Mesquita kept herself composed and scored a takedown, landing right into full mount. Mesquita landed ground-and-pound for about two-and-a-half minutes, completely controlling and dominating the action, busting Alekseeva up and nearly getting her out of the fight in the first round's closing seconds.

Bia Mesquita, "Lady GOAT," Thrashes Irina Alekseeva In Impressive UFC Debut At UFC Rio

Mesquita, known as "The Lady GOAT," is a multiple-time Brazilian jiu-jitsu world champion and a former ADCC champion. She entered tonight 5-0 in her MMA career, including a finish of Sierra Dinwoodie to capture the LFA women's bantamweight title at LFA 211 in June.

Alekseeva has now lost four of her last six, including three straight UFC losses. She won her UFC debut over Stephanie Eggar in April 2023 but missed weight.
