The First Encounter at Madison Square Garden

183 days (about 6 months) ago, Mayer and Ryan clashed inside the Hulu Theater at Madison Square Garden. What followed was an intense 10-round slugfest in front of 5,000 roaring fans. Mayer, now 34, used superior footwork and fast hands to dominate the early rounds. She opened it with a sharp right cross that caught Ryan flat-footed. Ryan, 31, from Derby, had her best showing in round nine, throwing heavy leather and pushing the pace. Still, the judges scored it 95-95, 96-94, and 97-93, crowning Mayer as the new WBO welterweight world champion and a two-weight world titleholder.

Grudge Match Origins

Their animosity began when Mayer accused Ryan of stealing her trainer after the British fighter joined her U.S. gym. Tensions escalated before the first fight when Ryan was shockingly doused with red paint outside her hotel. Mayer publicly condemned the attack, but Ryan suspected foul play, stating, “Who knew what time I was coming down from my hotel to the venue? They knew what time.” Things boiled over at the weigh-in when Ryan turned her back and refused to touch gloves with Mayer.

Styles Make Fights

Mikaela Mayer’s strategy was built around movement, angles, and timing. Her ability to pivot left and control distance frustrated Ryan, who struggled early. Ryan, however, thrives on pressure, and by round nine, her relentless output had Mayer trading punches in toe-to-toe exchanges. While Mayer absorbed big shots, she showed her durability and composure under fire. Ryan’s powerful attacks came with intent, but her tendency to load up early left her vulnerable to counters.

Adjustments for the Rematch

Ryan’s biggest flaw in the first bout was her slow start. She needs to bring that round-nine energy from the opening bell, closing the distance early and forcing Mayer into uncomfortable exchanges. On the other side, Mayer must stick to her blueprint—movement, jabs, and angles—while bracing for an even more aggressive Ryan. Whether Mayer can repeat her flawless execution or Ryan can disrupt her rhythm early may decide the outcome.

Psychological Warfare

The war of words is as fierce as the battle inside the ring. Ryan remarked, “You can see she loves the attention, the talk… When you do not give her that, it triggers her.” Mayer shot back, “Her coach wants to hide and stay in the shadows… I don’t do anything but speak the facts.” The verbal chess match adds another layer to the psychological game each fighter must master before stepping through the ropes again.

Fight Night Prediction

Their first bout was an all-out war, and this sequel is set for even higher intensity. Mayer followed her game plan to perfection last time, combining speed, IQ, and timing. Ryan’s surge in round nine showed she is capable of turning the tide, but she needs to bring sustained pressure from the jump. If Mayer repeats her execution, she can outpoint Ryan again—but it will not be easy. The pick: Mikaela Mayer to win on points in another brutal, high-level 10-round duel.
