Roger Federer came into 2014 looking to improve on his results after an extremely dissapointing season on court in 2013. He did well for himself at the Australian Open and the Monte- Carlo Masters before coming into the French Open. The Swiss entered theRound of 16 meeting withErnests GulbisatRoland Garroswith asuperb recordon the Grand Slam stage after winning the first set. Federer did manage to take the first set, but Gulbis had other ideas up his sleeve.

Gulbis proved too good for the 17 time Grand Slam Champion as he beat him in a thrilling five set match, which also ended Federers record of reaching nine straight French Open quarter-finals.

Its the biggest win of my career, Gulbis said in an on-court interview. Sorry I had to win. I know how everyone likes Roger. It was a tough match, but this is sport. Ive been playing very well in France. I won tournaments in Marseille and Nice, hopefully Paris is the next one."
