The Cincinnati Open final between Carlos Alcaraz and Jannik Sinner was set to be another thrilling chapter in their growing rivalry. Instead, it ended abruptly after just 22 minutes when Sinner, the world number one, was forced to retire due to illness. Trailing 5-0 in the first set and visibly struggling, the Italian called for medical attention before deciding he could not continue.

Alcaraz claims the title

With Sinner’s retirement, Alcaraz was awarded the Cincinnati Open title. Though the victory came under unfortunate circumstances, it marked Alcaraz’s third Masters 1000 title of the season and his sixth overall in this category. The Spaniard now holds a 9-5 head-to-head advantage over Sinner and continues to build an impressive resume at just 22 years old.

Sportsmanship and mutual respect

Following the match, Alcaraz expressed sympathy for his opponent, stating that it was not the way he wanted to win. He praised Sinner’s resilience and wished him a speedy recovery. Sinner, in turn, apologized to fans during the trophy presentation, explaining that he had felt unwell the previous day and hoped to improve overnight, but his condition worsened.

Implications for the US Open

Both players now turn their attention to the upcoming US Open. Sinner, who won the tournament last year, will be defending his title and top ranking. Alcaraz, currently ranked number two, has a chance to reclaim the number one spot if he performs well in New York. The abrupt end in Cincinnati adds an element of uncertainty to Sinner’s readiness, while Alcaraz enters the final Grand Slam of the year with momentum.
