Number one seed and reigning champion Serena Williams was stunned in the fourth round by 23rd seed Sabine Lisicki at Wimbledon 2013.
It was a match Williams was expected to win but her opponent had other ideas, producing a scintillating performance to thrill the Centre Court crowd and seal an incredible 6-2 1-6 6-4 win to go through to the quarter-finals.
Lisicki staged a fantastic comeback in her third round match with Sam Stosur and came flying out of the blocks in the first set in the first match on Centre Court.
Williams looked bemused that her opponent was serving so well and hitting winner after winner, it was her first real test of the Championships and she was not reacting well early on.
The 23-year-old was full of energy and her ultra-positive game was paying dividends against the five-time champion, breaking here twice to take the first set.
There is a reason Williams has been so successful at the All England Club and she looked more like herself at the start of the second set, breaking Lisicki’s serve the first time of asking.
The 31-year-old went up a level and stormed away with the second set 6-1, before braking again early in the third.
The Centre Court crowd were getting right behind the underdog Lisicki but even they would have doubted what would happen soon after.
Lisicki did not let the pressure get to her, however, and carried on attacking to produce some quite unbelievable results.
She broke back in the seventh game of the deciding set before saving four break points the next game.
Lisicki made it three games in a row by putting Williams under a lot pressure with her deep ground strokes – Williams was hitting more errors than usual and she just could not live with the German.
Lisicki was tasked with serving out for the match and she was evidently nervous, throwing up a double fault to give Williams a break point.
Aces saved two of these and she made no mistake when presented with her second match point, securing an astonishing and emotional victory.
“I’m still shaking, I’m so happy!” she said through tears of joy after the game.
“Serena played a fantastic match. Such a tough opponent. Amazing feeling. She played unbelievable tennis; I gave it everything I had. I just hung in there.”
Williams joins Roger Federer, Rafael Nadal and Maria Sharapova in being beaten by a lower ranked opponent in a Wimbledon tournament that is shaping up to be one of the most unpredictable ever.
Lisicki’s quarter-final opponent will be Kaia Kanepi, who knocked out home favourite Laura Robson in the first match on No.1 Court.
