Novak Djokovic lost to Mariano Navone in the first round of the U.S. Open during a five-set match on Sunday night [1, 2].
The defeat marks a significant downturn for the veteran player, who has not won a Grand Slam title in three years [3]. As one of the most decorated players in tennis history, Djokovic's early exit raises questions about his current form and physical longevity.
Navone secured the victory with a final score of 7-6, 5-7, 4-6, 6-2, 6-1 [1]. The contest lasted approximately five hours [2]. While the match was an endurance test, reports vary on whether it set a specific record for the longest Grand Slam opener [5].
Djokovic, who is 39 years old [2], struggled throughout the later stages of the match. Reports indicate he suffered from fatigue and physical illness, which hampered his ability to maintain pace against Navone [2, 4].
Navone continues to build a historic career trajectory. He previously became the first man in the Open Era to be seeded in his Grand Slam main-draw debut during the French Open [6]. His performance in New York demonstrates a high level of consistency against top-tier opposition.
The match took place at Flushing Meadows-Corona Park in New York [1, 2]. Djokovic entered the tournament as a former four-time champion, but he was unable to recover after losing the middle sets to the Argentine [6].
“Novak Djokovic lost to Mariano Navone in the first round of the US Open.”
This loss underscores a shifting guard in professional tennis. Djokovic's struggle with illness and age, combined with a three-year drought of Grand Slam titles, suggests the veteran is facing a decline in physical resilience. Conversely, Navone's victory reinforces his status as a rising force capable of dismantling established champions in high-pressure environments.
