This is one of the most lopsided rivalries you will find between two elite competitors. Across 9 recorded meetings, Beatriz Mesquita has beaten Bianca Basilio every time, going 9 to 0 with no draws. The meetings span from 2016 to 2022 and covered both gi and no-gi, from round robins to finals, so this was not a matter of one bad matchup on one day. Basilio never solved her.

The way Mesquita won says a lot about the styles. Five of the 9 wins came by submission, and the finishes were varied: a Straight Ankle Lock on two separate occasions, a Rear Naked Choke in the 2017 ADCC World Championships final, and a Kneebar at the Abu Dhabi World Professional Jiu-Jitsu Championship 2016 final. That is a leg game and a back game working together, which is hard to defend against over a full match. The two meetings that were not submissions or standard decisions went to overtime at EBI 16 and to a straight decision at Abu Dhabi Queen of Mats, so even when Basilio extended the match she did not turn the result.

On their own records the two are closer than the head to head suggests. Both sit at a 70% win rate, with Mesquita at 62 wins and 27 losses over 89 recorded matches and Basilio at 101 wins and 44 losses over 145 recorded matches. Mesquita finishes 47% of her wins and Basilio 42%. The gap in this rivalry was not overall quality, it was that Mesquita held every stylistic answer when the two faced each other.
