Australian open nadal knocked first round
You're referring to the 2014 Australian Open!
Yes, Rafael Nadal was knocked out in the first round of the 2014 Australian Open by Fernando Verdasco, losing in five sets, 7-6(4), 4-6, 3-6, 7-6(1), 6-7(4).
This was a major upset, as Nadal was the second seed and had been in excellent form leading up to the tournament. Verdasco, on the other hand, was a wildcard entry and had never beaten Nadal in a Grand Slam match before.
The loss was a significant setback for Nadal, who was looking to win his second Australian Open title. However, he has since bounced back and has had many successful tournaments, including winning multiple Grand Slam titles.
