Djokovic holds the all-time record with 40 Masters 1000 title triumphs as well as the men's all-time record of 24 majors.
So, early rounds defeats are a rare occurrence for the 'Hall of Fame' Serbian.
World No.123 Nardi's incredible showing meant he is the lowest-ranked player to down Djokovic at the Masters or Grand Slam level ever.
On top of that, Nardi was ready to leave California for his next tournament, but signed up on the 'Lucky Loser' list, having fallen to David Goffin in the final round of qualifying last week. What a turnaround for the Italian.
"I think that before this night no one knew me," said Nardi, recording just his fifth tour-level victory on Monday. "I hope that the crowd enjoyed the game. I'm super happy with this one."
Nardi advances to face Amercian No.17 seed Tommy Paul to vie for a quarter-final ticket.
