Marion Bartoli revealed that an emergency power nap helped her surge into the Wimbledon final following her 6-1 6-2 defeat of Kirsten Flipkens.
Bartoli found a quiet corner in the dressing rooms and slept for half-an-hour as Centre Court assembled for the first women's singles semi-final of the day.
And the rest brought the best out of the Frenchwoman as she raced past her Belgian opponent to set up a final against Sabine Lisicki.
"You can ask the physio in the locker room. I slept from 12pm to 12.30pm," she said. "Right before going on, and you can see I was razor-sharp today," said Bartoli, who lost the 2007 final to Venus Williams.
"I felt I was just maybe a bit tired and I needed a quick nap to recover from my early-morning practice."
"I felt I deserved it," Bartoli said. "I believe as a sportsperson you cannot always have highs, and you have to go through some low moments to enjoy the highs even more.
"Even if I was having some hard times outside of the court, I was still able to go on the practice court every day and practise hard. I felt because I put that in, I should have a reward from it. Obviously I have had that this year."
'Flipper' to her friends, family and fans, she had the majority of the crowd on her side against Bartoli, willing a contest to develop, but a knee problem proved a hindrance.
Flipkens admitted she was troubled by a knee injury, adding: "I'm not going to use it as an excuse.
"I fell in the first set. Straightaway I didn't feel anything, but I fell on my bad knee. A couple of games later I started to feel a really sharp pain.
"I tried my slices, and she didn't have any problem with that. I tried the drop-shot, and she got it. I played a passing shot, and she came to the net. I tried a lob... I tried everything, actually. It didn't work out."
