The former Australian Open winner was a surprise semi-finalist here last season, proving he had truly recovered from a career-threatening knee injury. A penetrating serve earns him plenty of cheap points, while no-one wins a Grand Slam without decent groundies too. To-Jo's preparation has been hindered by a freak eye injury - a ball hit him during a practice session - and as a result he is still feeling his way back. Therefore it looks unlikely he'll repeat last year's run.
