Casey O'Neill
Eduarda Moura

UFC 331 gets a sneaky good flyweight fight here, because Casey O'Neill and Eduarda Moura arrive with totally different kinds of pressure. O'Neill has won 2 straight, capped by the round 1 stoppage of Gabriella Fernandes at 3:11. Moura is trying to answer a decision loss to Wang Cong after decision wins over Lauren Murphy and Veronica Hardy. Here's the thing: O'Neill wants a busy fight where her hands keep coming and Moura never gets comfortable. Her 69 inch reach gives her a small advantage over Moura's 67, but Moura can erase that space by changing levels, driving to the fence, and making every exchange feel heavy.
- O'Neill brings 2 straight wins and serious early pressure
- Moura's takedowns can turn clean striking exchanges into ugly scrambles
- Only 2 inches of reach separate two very different rhythms
The fight is most likely to break open late in round 1 or early in round 2, when the pace rises and clean space starts turning into rushed entries and scrambles.
One woman wants speed and room, while the other wants contact and control. On the feet, O'Neill has to keep her stance under her while throwing volume, because wild combinations can open a clean lane for a takedown. Moura landed 3 takedowns even in the loss to Wang, and everyone remembers the punches from mount that stopped Montserrat Conejo Ruiz. That is the danger in every scramble. Moura cannot hang outside and let O'Neill set the speed, while O'Neill cannot accept long clinches or get stuck underneath.
The battle after the first defended shot could tell us more than the opening punches. Both women have already shown they can handle 3 hard rounds, so this is not just about an early burst. It is about who can force her kind of fight when the first plan starts getting messy.
