Novak Djokovic’s endurance could face grueling test at U.S. Open

New York – Novak Djokovic aims to secure his record 25th Grand Slam title at the U.S. Open, but his pursuit raises concerns about whether his 39-year-old body can endure tennis's grueling fortnight. The four-time U.S. Open champion has reached a record 10 finals in New York. Winning a third title at Flushing Meadows would surpass Margaret Court's 24 Grand Slam singles records, putting Djokovic alone at the top.

He reached the Australian Open final this year after a five-set semifinal win against Jannik Sinner, and also advanced to Wimbledon's semifinals. However, Djokovic's Cincinnati Open defeat earlier this month highlighted the physical toll he must manage. After losing to Thiago Agustin Tirante in the second set due to high humidity and heat, Djokovic revealed the issue to reporters.

"It’s simply a health issue I have," he stated. The situation emphasizes the challenges of the final Grand Slam of the season, which includes late-summer heat, heavy humidity, hard courts, and seven intense matches. Although Sinner's withdrawal due to a knee injury took one formidable opponent off the table, reigning champion Carlos Alcaraz, along with Alexander Zverev, Ben Shelton, Taylor Fritz, and younger players, pose significant threats.

Djokovic's experience is his greatest advantage, as he can withstand pressure and adapt during long matches. However, he has fewer opportunities for error in his later career years. A favorable draw, effective service games, and short opening-week matches could help him conserve energy for the final stages, especially since his record-breaking effort may hinge on his body keeping up with his ambitious pursuit.
