CINCINNATI -- CINCINNATI (AP) — Novak Djokovic pulled out of the Cincinnati Open on Monday for what officially was listed as a “non-medical” reason, meaning he will head to the U.S. Open without having played a match in about 1 1/2 months.

Djokovic, ranked No. 6 in the world, is bidding to win a record 25th major at the U.S. Open, which begins Aug. 24. He lost to world No. 1 Jannik Sinner in the semifinals at both Roland Garros and Wimbledon. The Cincinnati Open is still headlined by Sinner and Alcaraz, with many other top stars playing.

Novak Djokovic withdrew from the Cincinnati Open on Monday and will miss the tournament for the second straight year.
