Beatriz Mesquita and Ffion Davies have met 4 times on record, and the series sits level at 2 wins each. What stands out is the venue: three of those four meetings happened at ADCC, with the fourth coming in the gi at the 2019 Abu Dhabi World Professional Jiu-Jitsu Championship. This is a rivalry built at the top of the no-gi bracket more than anywhere else.

The meetings split cleanly by era and by attire. Mesquita took the first two, a quarter-final Armbar at the 2017 ADCC World Championship and a points win in the gi final at Abu Dhabi in 2019. Davies then took the next two, both at ADCC semi-finals: an armbar finish at the 2019 ADCC World Championship and a points decision at the 2022 ADCC World Championship. Two of the four were finished by submission, and in both cases the finish was an armbar.

Both women are heavy finishers overall. Mesquita's recorded win rate is 73% with 53% of her wins by submission, while Davies sits at 80% with 56% of her wins by submission. Interestingly, the armbar is the favorite submission for each, with 15 wins by that method on record for both. The common-opponent data shows they solve different problems: Mesquita is 11-0 against Bianca Basilio where Davies is 1-3, while Davies is 4-2 against Nathalie Ribeiro where Mesquita is 0-1.
