Novak Djokovic's stunning run at the majors hit a wall on Sunday night, as the 39-year-old fell in five sets to unseeded Mariano Navone in the first round of the US Open. It's his earliest exit at a major since the 2006 Australian Open, snapping a streak of 78 straight opening-round wins at Grand Slams.

Djokovic looked visibly unwell throughout the match, and the loss extends a title drought that now stretches back three years.

Hint: It matches Margaret Court's all-time record, which he tied at the 2023 US Open.
