Nishikori Federer's bogeyman

A TIRELESS Kei Nishikori shocked 17-time grand slam winner Roger Federer 3-6 7-5 6-4 yesterday to claim his second top-five scalp in two days and reach the semi-finals of the Sony Open in Miami.

After knocking off fourth-seeded Spaniard David Ferrer in a three-hour marathon on Tuesday, the 21st ranked Japanese man was forced to go the distance again, surviving a two-hour centre court battle with Federer. Nishikori has been one of Federer's few bogeymen, having now gotten the better of the Swiss maestro in two of their three career meetings.

The victory set up a semi-final meeting against world number two Novak Djokovic, who ended Andy Murray's reign as Miami champion by easing past the sixth seeded Briton 7-5 6-3.
