Earthquake in Flushing Meadows! Novak Djokovic Stunned by Mariano Navone in US Open First Round

 The opening night of the 2026 US Open witnessed one of the biggest upsets in modern tennis history. 4-time champion and 24-time Grand Slam winner Novak Djokovic was knocked out in the first round at Flushing Meadows, falling to Argentina's Mariano Navone in a five-set thriller.

The 39-year-old Serbian, seeded 4th in the tournament, struggled with physical fatigue and uncharacteristic unforced errors under the bright lights of Arthur Ashe Stadium.

Match Summary: How the Epic Unfolded

• Set 1 (Navone 7–6): Djokovic rushed to an early 4–1 lead, but Navone fought back fiercely to force a tiebreak. The Argentine took the first set, handing Djokovic his first US Open opening-set loss in 20 years.

• Sets 2 & 3 (Djokovic 7–5, 6–4): The veteran regrouped with tactical brilliance, winning 9 consecutive points in the second set and grinding out the third to lead 2–1 in sets.

• Set 4 (Navone 6–2): Navone targeted Djokovic’s second serve, breaking twice to force a deciding fifth set as Djokovic appeared physically spent.

• Set 5 (Navone 6–1): Dominated by the young Argentine, who closed out the match with high-intensity baseline play to seal a monumental victory.

My Analysis & Prediction

Tactical Takeaway: Novak Djokovic's 10 double faults and a low 55% first-serve percentage were critical downfalls. Mariano Navone capitalized on Djokovic’s lack of hard-court match sharpness following his early Cincinnati exit. Navone extended baseline rallies, forcing Djokovic into long exchanges that physically wore down the 39-year-old in the hot and humid New York evening.

Tournament Prediction: This shock loss completely opens up Djokovic's section of the draw. For Mariano Navone, this career-defining win will give him immense momentum. Expect Navone to ride this confidence into a deep run, reaching at least the 3rd round (3–1 win in Round 2).
