Wimbledon 2013 is serving up shocks at regular intervals it seems, but Manic Monday may well have seen the biggest shock of the tournament yet.
Serena Williams had looked imperious in here march to the fourth round and seemingly inevitable march to a sixth Championship.
However, young German Sabine Lisicki had other ideas and produced two periods of outstanding, swashbuckling grass court tennis to pull off a terrific upset.
Williams went down 2-6 6-1 4-6 in possibly the game of the tournament so far and the world number one joins the likes of Roger Federer, Rafael Nadal and Maria Sharapova in exiting the draw earlier than predicted.
Lisicki get a quarter-final clash with Kaia Kanepi after the Estonian ended Great Britain’s hopes of a fairytale by defeating Laura Robson.
The British number one is ranked higher than her 28-year-old opponent, but it seems as though age was a key factor because Kanepi showed greater maturity during the big points.
The men’s final that many seem to be predicting between number one seed Novak Djokovic and number two seed Andy Murray is still on course to happen, as both made it through to the quarter-finals.
Djokovic survived a second set wobble to defeat 13th seed Tommy Haas in straight sets, but he was made to work for it after a straightforward first set.
The Serb started much the better of the two but Germany’s Haas eased into the game and even squandered a break in the second set.
Djokovic eventually triumphed 6-1 6-4 7-6 to set up a quarter-final against seventh Tomas Berdych, who saw off a stiff challenge from Australian to come through in four sets 7-6 6-7 6-4 6-4.
Murray’s match against Mikhail Youznhy on Centre Court also saw the favourite of the two players suffer from second set wobbles and the Russian even served for the second set at one point.
This is a new Andy Murray, however, and he is not so prone to slumping in response to moments of bad form or luck.
Youzhny could not get the job done and required some medical attention after losing the second set on a tie-break and he come out for the third with a the look of a beaten man.
The home favourite eventually ran out 6-4 7-6 6-1 winner and will face Spain’s Fernando Verdasco in the quarters, who beat France’s Kenny De Schepper in straight sets.
Fourth seed David Ferrer overcame a first set blip to beat Ivan Dodig of Croatia 6-7 7-6 6-1 6-1 and will meet Juan Martin del Potro in the next round.
Del Potro has always had the game for grass and he now looks as though he is beginning to believe it, as he is improving with every round – the eighth seed eased past Andreas Seppi 6-4 7-6 6-3.
The final men’s singles quarter-final, taking place on Wednesday, will be a historic one, as the meeting between Poland’s Jerzy Janowicz and Lukasz Kubot will be the first time two players from that nation have made a Grand Slam quarter-final.
As they are playing one another it will guarantee the first ever Polish Grand Slam semi-finalist – they are also making history the hard way.
Both men came through five set matches, with Janowicz defeating Jurgen Melzer of Austria and Kubot overcoming Adrian Mannarino of France.
