Novak Djokovic reached the Australian Open fourth round with a straight-set win over Botic van de Zandschulp, but the match was marred by a risky moment. The 38-year-old smacked a ball away that narrowly missed a ball girl, evoking memories of his 2020 US Open disqualification. He apologized, calling it a heat-of-the-moment reaction.

The incident occurred when Djokovic casually hooked a ball left after a point, risking a default under Grand Slam rules for dangerous or reckless ball abuse. Former champion Pat Cash noted he was "three inches" from disqualification. This scare came as Djokovic also fell awkwardly and received treatment for a blister, adding to his physical concerns.

Despite the drama, Djokovic secured his 400th Grand Slam victory without dropping a set, preserving energy for his title pursuit. He now faces Czech 16th seed Jakub Mensik in the next round. Meanwhile, Stan Wawrinka's Melbourne farewell ended with a four-set loss to Taylor Fritz, capping his final Australian Open appearance.
