Djokovic clings onto unbeaten run

Novak Djokovic came through one of the toughest tests of his unbeaten season to date to extend his extraordinary winning streak to 30 matches and book his place in the Mutua Madrid Open semi-finals.

Djokovic needed two hours and 27 minutes to see off home favourite David Ferrer, a finalist in consecutive recent events in Monte Carlo and Barcelona, and set up a last-four clash with Brazil’s Thomasz Bellucci.
