UFC 331 results: Casey O'Neill pulls off impressive reversal directly into a submission to best Eduarda Moura

Casey O'Neill delivered an astonishing performance on the early prelim card of UFC 331, pulling off an impressive reversal directly into a submission against her opponent Eduarda Moura. In the first round, Moura had been dominating the fight, holding top mount. O'Neill, however, showcased her remarkable agility as she utilized her legs, positioned them on Moura's hips, extended them, and flipped her over.

While executing this move, she simultaneously shifted her hips and locked in an armbar, causing Moura to tap out almost immediately. This incredible transition to an armbar showcased O'Neill's exceptional skill and speed. Moura had controlled the fight for nearly the entire duration before O'Neill's breathtaking reversal. The fight began with O'Neill attempting a low kick, which Moura countered with a right jab, momentarily disorienting her opponent.

Despite this initial setback, Moura quickly regained her composure and worked towards landing her flip reversal. UFC commentator Joe Rogan noted that he had never witnessed a move quite like this before, and Moura confirmed that she had practiced the maneuver before. With this victory, O'Neill's record improved to 12-2, while Moura's loss dropped her to 12-2.

This win marked O'Neill's third submission victory in her professional MMA career, making it back-to-back losses for Moura, who had previously faced defeat in a unanimous decision against Wang Cong and another unanimous decision loss to Lauren Murphy.
