Klizan will have earned his corn here, that's for sure. Djoker, Feli, now Nadal.
Surprised Dimitrov had so much trouble with Jaziri. You usually only hear about Jaziri when Marrakech comes around.
Dimitrov probably shouldn't have let Jaziri trouble him so much. Relies too much on "talent," imo, and gets muddled as to his game plan...if he ever actually comes out with one. Jaziri maybe pulled a little gamesmanship towards the end of the 3rd. Called the doctor for upset stomach at 5-4, when GD was about to serve to stay in. Had Annacone's head a bit on fire, at the rule. Also, Annacone thinks that Grigor could trouble Rafa, if he'd play him "the right way." Well, that's easier said than done, especially with Grigor.
As to who can beat Nadal going forward this clay season, which seems to be the parlor game we're going to play for the next 6 weeks, I'm going to add Tsitsipas to the list of potentials. I do realize I'm at the risk of bandwagoning him. But he has identified clay as his preferred surface, in the interview you posted above. He has a 1HBH, though
@mrzz insists that's not a liability. He's 6'4", which is tall enough to take the high ball, but not so tall that he's not a good mover. He has some soft hands. And he has the arrogance of youth. I'm not saying at RG, but he could spoil Rafa in best of 3, if he falls in his draw early. Just a thought.
