Top-ranked Jannik Sinner has become the first player to advance to the semifinals at the ATP Finals in Turin. Sinner was assured of a spot in the last four after U.S.

Taylor Fritz, the U.S. Open finalist who lost to Sinner in New York, was also drawn in the Italian’s group alongside Australian Alex De Minaur, making his ATP Tour Finals debut; Casper Ruud and Andrey Rublev, who qualified as world No. 9 after Novak Djokovic withdrew, rounded out the second group.

Andrea Gaudenzi said at the ATP Finals that anyone hinting that a “double standard” was applied because of top-ranked Jannik Sinner’s status is “unfair because the rules have been the same.”
