Carlos Alcaraz was crowned the 2025 Cincinnati Open champion in unfortunate circumstances after World No. 1 Jannik Sinner was forced to retire due to injury. The much-anticipated final ended early in the first set, with Sinner trailing 0-5 when he pulled out, handing Alcaraz his first title in Cincinnati and his sixth trophy of the season.
The final had promised to be a thrilling encounter between the top two players in the world, but it was cut short by Sinner’s physical struggles. Despite the anticlimactic finish, the result marks another major milestone for Alcaraz, who continues to build an impressive résumé in 2025.
For Sinner, the retirement was a heartbreaking end to a dominant run in Ohio. The Italian came into the tournament as the defending champion and had not dropped a single set on his way to the final. His form on hard courts has been nothing short of remarkable over the past year.
The Italian was riding a 26-match winning streak on hard courts, one of the longest in recent ATP history. That streak included title runs at the 2023 Shanghai Masters, the 2023 ATP Finals, and the 2024 Australian Open. It was a showcase of his consistency and growing dominance on the surface.
His last defeat on a hard court came almost a year ago in Beijing, where, coincidentally, it was Alcaraz who managed to snap his winning run. In that match, Alcaraz came from a set down to win in three, underlining the evenly matched nature of their rivalry.
This time, Alcaraz’s road to the final in Cincinnati was a little bumpier. Unlike Sinner, the Spaniard had to battle through tougher encounters, dropping two sets en route to the title match. However, his resilience and shot-making under pressure were once again on full display.
Despite the challenges, Alcaraz’s consistency has been a highlight this season. Reaching his seventh straight tour-level final, the 22-year-old is proving that he belongs at the very top of the men’s game. Cincinnati marked his second final at the tournament, following his dramatic loss to Novak Djokovic in the 2023 classic.
The ongoing rivalry between Sinner and Alcaraz has become one of the most compelling storylines in men’s tennis. Their contrasting styles and shared generational status have produced multiple memorable matches, adding excitement and narrative depth to every encounter.
With this latest win, Alcaraz extended his head-to-head lead over Sinner to 8–5. Earlier this season, he had notched five straight wins against the Italian, including victories in Rome and at Roland Garros, further solidifying his psychological edge in crucial matchups.
However, Sinner proved his ability to turn the tide at Wimbledon, where he beat Alcaraz in four sets to win his first title at the All England Club. That match was a statement performance and showed that their rivalry remains tightly contested despite Alcaraz’s recent edge.
Adding to the stakes of the Cincinnati final was the looming battle for the No. 1 ATP ranking. With both players vying to enter the US Open at the top of the leaderboard, the result in Ohio carried implications that went beyond the trophy itself.
Sinner currently holds a 2,250-point lead in the rankings, but much of that advantage comes from his title run at the 2024 US Open. Alcaraz, on the other hand, made an early exit last year, losing in the second round—a result that puts him in a strong position to gain ground once the points reset.
Had Sinner successfully defended his Cincinnati title, he would have extended his lead and created a 650-point buffer heading into Flushing Meadows. But with Alcaraz winning, the gap narrows, potentially setting up a change at the top once the US Open concludes.
If Alcaraz performs well in New York and Sinner fails to defend his points, the Spaniard could reclaim the No. 1 ranking. In fact, once the 2024 US Open points are removed from the calculation, Alcaraz could leapfrog Sinner by as much as 50 points, depending on their respective performances.
The final in Cincinnati may not have delivered the match fans hoped for, but it was still a significant moment in the 2025 season. Alcaraz adds another title to his growing collection, while Sinner faces questions about his fitness with the season’s final major just around the corner.
As both men prepare for the US Open, their rivalry and ranking battle remain central to the ATP Tour narrative. Whether Sinner can recover fully and defend his crown, or Alcaraz can reclaim the top spot and seek redemption in New York, the next chapter promises high drama on the hard courts of Flushing Meadows.
