Jannik Sinner has been the man to watch this summer, riding a scorching win streak as he heads into the Cincinnati Open semifinals. On Saturday, he’ll face French breakout star Terence Atmane with a spot in the final — and a 26th straight hard-court victory — on the line.

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.
