World number one Jannik Sinner expressed optimism regarding his hip issue as he prepares for the Cincinnati Open, a crucial tune-up for the U.S. Open. After struggling with the injury since May and experiencing a setback during a quarter-final loss in Montreal, Sinner attributed his difficulties to match intensity following a brief absence due to tonsillitis. He reassured reporters, stating, 'I feel quite good' and emphasized his eagerness to return to the court. Sinner acknowledged that the Cincinnati conditions might pose a challenge, but he views this tournament as vital for building confidence ahead of the U.S. Open, which runs from August 26 to September 8. He has a few days to prepare and is hopeful to demonstrate good performance in his upcoming matches.
