Argentina’s Mariano Navone pulled off one of the biggest upsets in recent tennis history as he defeated 24-time Grand Slam winner Novak Djokovic in the first round of the US Open on Sunday. Navone beat the Serbian great 7-6(5), 5-7, 4-6, 6-2, 6-1 in a four-hour and 36-minute battle at Arthur Ashe Stadium. The result ended Djokovic’s impressive record of getting past the first round at a Grand Slam, which had stood since the 2006 Australian Open, according to the ATP website.&nbsp;Djokovic managed to win the third set and looked in control at times, but the 39-year-old struggled physically as the match went on. He appeared to have problems with his movement and was seen vomiting on court several times during the contest.&nbsp;After dropping the fourth set, Djokovic had chances to fight back, but Navone stayed calm and took control of the deciding set. The Argentine produced a strong performance to secure the biggest victory of his career.&nbsp;Navone had entered the match with a poor record on hard courts, having won only 12 of his previous 41 tour-level matches on the surface, however, he kept his composure in the crucial moments. On match point, he chased down a drop volley and sent the ball into the open court to seal the victory. He then shared a warm moment with Djokovic at the net.&nbsp;Also Read - <a href="https://www.wionews.com/sports/deepti-sharma-becomes-all-time-leading-wicket-taker-in-women-s-t20is-1788151167260">Deepti Sharma becomes all-time leading wicket-taker in Women’s T20Is</a>&nbsp;Djokovic, a 101-time ATP title winner, also took time to sign autographs for fans before leaving Arthur Ashe Stadium.&nbsp;The loss ended Djokovic’s hopes of winning a record 25th Grand Slam title at this year’s US Open.
