The highly anticipated final between two of the world's top players ended unexpectedly. Sinner, feeling unwell since the previous day, battled through challenging conditions with temperatures around 31°C and 57% humidity. The Italian player showed visible signs of fatigue and ultimately retired after receiving medical attention.

Alcaraz secured his first Cincinnati Open title after a final lasting just over 20 minutes. This is Alcaraz's eighth ATP Masters 1000 title at the age of 22, matching Rafael Nadal's record at a similar stage in his career. It's also his third Masters 1000 title this year, following victories in Monte Carlo and Rome.

"I didn't want to win this way," Alcaraz said after the match. "Sinner is a true champion, and I believe he will come back stronger after this."

Sinner's retirement ended his 26-match winning streak on hard courts. Before retiring, the 24-year-old had four winners, double that of Alcaraz. However, Sinner committed nine unforced errors compared to Alcaraz's one.

Sinner's health issue puts his participation in the US Open mixed doubles, starting today, in doubt. He recently partnered with Katerina Siniakova after Emma Navarro withdrew to focus on the singles event elsewhere.

In the ATP Race To Turin rankings, which determines the year-end world number one, Alcaraz currently leads Sinner by 1,890 points. The Spanish player has 54 wins and six titles this season, the most on tour. He improved his head-to-head record against Sinner to 9-5, including six wins and two losses on hard courts.
