Novak Djokovic faced a tough challenge on and off the court during his second-round match at the Australian Open. The Serbian tennis superstar confronted a heckling spectator and exchanged words during his 6-3, 4-6, 7-6(4), 6-3 victory over home favorite Alexei Popyrin.

The incident occurred when Djokovic, who holds a record 24 grand slam men's singles titles, including 10 Australian Open titles, reached his tipping point after tolerating comments from the spectator throughout the match. Djokovic invited the heckler to come down and say what was on his mind face-to-face but received no response.

Djokovic admitted that the confrontation may have sparked something in him, as he had felt "quite flat" during stretches of the match. The world No. 1 expressed his disappointment with spectators crossing the line but emphasized his support for fans to enjoy themselves while adhering to respectful boundaries.

This win was not easy for Djokovic, as he struggled for consistency and dropped sets in both his opening-round match against Dino Prižmić and in the second round against Popyrin. Despite hitting 32 unforced errors, Djokovic's experience and tactical adjustments helped him secure the win.

The turning point of the match came in the 10th game of the third set when Djokovic saved four set points, denying Popyrin the opportunity to take a 2-1 lead. The 24-time grand slam champion managed to turn the momentum in his favor and clinched the victory in four sets.

Looking ahead, Djokovic will face Argentina's 30th seed, Tomás Martín Etcheverry, in the third round. As he aims to raise his level and find his best form, Djokovic hopes to retain his position as a top contender in the tournament.

In other Australian Open news, Coco Gauff, currently ranked world No. 4, continued her impressive unbeaten start to 2024 with a 7-6(2), 6-2 victory over compatriot Caroline Dolehide. The talented young American will now face another American, adding to the growing anticipation for their highly anticipated clash in the third round.

As the tournament progresses, Djokovic and Gauff will look to build on their performances and make their mark in the Australian Open. Fans around the world eagerly await their next matches and hope to witness more thrilling moments on the court.
