US Open champion Jannik Sinner has provided a scare before next week’s tournament after he retired from the Cincinnati Open final against Carlos Alcaraz.
Sinner was only on court for 24 minutes, but was out of sorts in hot conditions in Ohio and broken three times by rival Alcaraz to trail 5-0.

With Alcaraz about to serve for the set, four-time grand slam champion Sinner called for the trainer and decided to quit to hand the world number two a maiden Cincinnati Open title and cast doubt over his involvement at Flushing Meadows, where the action gets under way on August 24.
