Round-by-Round Analysis: Wrestling vs. Striking
The three-round contest was a perfect microcosm of the classic MMA dilemma: what is more valuable, control or damage?
- Round 1: Bautista's Control. Bautista came out with high volume, pressing Aldo against the fence and utilizing significant clinch control. While Aldo defended well and landed solid counter-shots, Bautista’s positional dominance and activity were enough for at least one judge to score the round in his favor. This round set the tone for the fight's scoring ambiguity.
- Round 2: Aldo's Striking. The former champion found his rhythm, showcasing his trademark striking prowess. Aldo landed the cleaner, more powerful, and arguably more damaging strikes, visibly rocking Bautista at least once. This round was a clear victory for Aldo on most unofficial scorecards, highlighting his superior striking accuracy and power.
- Round 3: The Deciding Factor. The final round was the most contested. Bautista returned to his grappling-heavy approach, securing takedowns and maintaining top control for extended periods. Aldo, however, continued to land effective strikes, especially on the break and during stand-up exchanges. The judges were forced to weigh Bautista's time of control against Aldo's impactful striking.
The official result was a Split Decision victory for Mario Bautista (29-28, 28-29, 29-28). This meant two judges scored the fight 29-28 for Bautista, while one scored it 29-28 for Aldo. The key to Bautista's victory lay in the judges' prioritization of his wrestling control and cage pressure in the first and third rounds over the perceived damage inflicted by Aldo.
The Aftermath: Cries of "Robbery" and the Future of Both Fighters
The announcement of the split decision was immediately met with a chorus of boos from the crowd and widespread outrage across social media and the MMA community. The term "robbery" was frequently used, with many analysts and fans arguing that the damage and effective striking landed by the UFC Hall of Famer should have outweighed Bautista's control time.
The Controversy Explained: Damage vs. Control
The fight perfectly encapsulated the ongoing debate about the unified rules of MMA judging. Aldo's supporters argued that the criteria prioritize Effective Striking and Grappling (damage and immediate impact) above all else, and Aldo clearly landed the more impactful shots. Bautista's supporters, and the two judges who scored for him, focused on the criteria of Effective Aggressiveness and Cage Control, where Bautista's constant pressure, takedown attempts, and clinch work were dominant factors. The result highlights the subjective nature of scoring close rounds, especially when one fighter controls the position and the other controls the damage.
What’s Next for Mario Bautista?
Despite the controversial nature of the win, Mario Bautista secured a massive name on his resume and a spot firmly within the top 15 of the Bantamweight division. His momentum continues, as he is currently slated to headline a future UFC Fight Night event. His next challenge is a main event bout against Vinicius Oliveira on February 7, 2026, at the UFC Apex. A convincing win over Oliveira would silence the critics and solidify Bautista's position as a legitimate contender in one of the UFC's most stacked divisions.
What’s Next for José Aldo?
For José Aldo, the controversial loss to Bautista was a heartbreaking setback in his quest for a final title run at Bantamweight. The loss, unfortunately, contributed to a final decision regarding his career. Following the Bautista fight, Aldo competed again but ultimately decided to step away from the sport. Reports indicate that José Aldo officially announced his retirement from MMA, stating that no fight would convince him to return to the Octagon. This final retirement marks the end of an era for one of the sport's true legends, whose final chapter was marred by a contentious decision at UFC 307.
