Nikolay Davydenko

Davydenko's best result in a Grand Slam tournament was reaching the semi-finals, which he accomplished on four occasions: twice each at the French Open and the U.S. Open, losing to Roger Federer in all but one of them. He is regarded as the greatest player in men's tennis history not to have contested a Grand Slam final.
