Sinner turned 24 years old on Saturday, while Alcaraz is 22. All of this is to say it’s not a surprise that top-ranked Sinner and Alcaraz are meeting in the finals of the 2025 Cincinnati Masters, one of the biggest non-Grand Slams on the tennis calendar and the warmup event for the U.S. Open.

The highly-anticipated final at the Cincinnati Open came to a sad ending on Monday, as World No. 1 Jannik Sinner was forced to retire from the match against No. 2 Carlos Alcaraz while trailing 5-0 due to illness. With the result, Alcaraz wins his third Masters 1000 title of the season and his eighth overall in his storied young career.
