Roger Federer is out of the French Open after a surprise five set defeat to 18th seed Ernests Gulbis.
The Latvian won 6-7 (5-7) 7-6 (7-3) 6-2 4-6 6-3 to earn a shock win over the 17-time Grand Slam champion in three hours 42 minutes.
The loss for the 32-year old Swiss star means he has failed to make the quarter finals at Roland Garros for the first time since 2004.
Federer looked in control when he served for a two set lead - an advantage Gulbis surely wouldn't come back from - but contrived to hit a smash into the net on set point which gave the Latvian some hope.
He went on to take the second set on a tie break and then went ahead after winning the third 6-2, but once again the pendulum swung and Federer leveled at two sets apiece.
Although the momentum looked to be with Federer, Gulbis shocked the partisan crowd who were clearly behind the Swiss by claiming a tense final set - which included a lengthy medical time out from the 25-year old - and he will now face Tomas Berdych.
It was a typically flamboyant performance from Gulbis, who dazzled with some stunning winners yet also found the time to smash his racket and get into a verbal exchange with a member of the crowd.
"It was probably the biggest win of my career," Gulbis said.
"I have a new coach and it is working good. I hope I won over some of the fans and have a few more when I play Tomas Berdych next."
Many had touted Gulbis to be a potential star but he has never quite kicked on from a promising career as a youngster and he added: "I did a lot of bad decisions career-wise. Not paying enough attention to my body and how to practice.
"I'm 25 so this is my last chance to be really successful. I don't regret it at all because I'm in a better position - maybe not as a tennis player but as a person."
