Rafael Nadal was stunned by little-known Lukas Rosol 6-7, 6-4, 6-4, 2-6, 6-4 in the second round of Wimbledon on Thursday.
Looking nothing like the player who has won 11 Grand Slams, the Spaniard stumbled, complained and bumped his way to a shock loss.
After coming back in the fourth set to make it 2-2, Nadal lost his composure completely after the decision to put the roof on was made as light faded. The Spaniard could not stay with the man from the Czech Republic, ranked 100, and went down tamely in the final set to make his earliest exit at Wimbledon since 2005.
Asked about the decision to delay the fifth set and close the roof, Nadal said: "That sure was not the best decision for me.
"But, that's what it is. I accept it; accept that he came back and played unbelievable.
"I was playing well in the fourth. I think I played a great fourth set, sure the stop did not help me, but that's how it goes.
"I think in the fifth set, he played more than unbelievable. First three sets, I didn't play well.
Nadal said he would now go back home and take some rest to recharge his batteries for the upcoming hard-court season.
"Now the only thing that I can do is, go back home and rest that I need and I deserve, so that's what I can do now and nothing else.
"I'm not very very disappointed, sure I am sad. But it is a second round match, not a semi-final or a final. A loss in the final rounds would bother me more. Because then you feel that you had the chance to win the title.
"Last four months were great for me, probably the best of my career, playing unbelievable in the clay-court season.
"You come here; you have a little bit of everything. You play against an inspired opponent and well I am out. It's not a tragedy; it is only a tennis match.
"There are much more important things in life."
Rosol said he could not believe he had beaten Nadal. "I still don't know (how I feel). There are just so many emotions, I didn't expect that I can win.
"I'm sorry for Rafa, but you know today I was somewhere else and I'm really happy for this.
"I still can't find the words, I still don't believe it.
"But it's just like a dream for me."
Rosol admitted the roof gave him an advantage. "Of course it (benefited). There was no wind, but I thought it was all about the first game of the final set. It gave me belief, if I could just hold serve, I could maybe win.
"It is the best win of my career. I never thought it was possible. Playing here on Centrecourt and to beat Rafa was unbelievable."
