Murray. Backed it up more effectively. Didn't face an injured opponent in the semi-final. Has clearly had a much stronger career overall.
But both are evidently legitimate. All slams are.
Are you kididng me
? Yeah, he was very lucky he avoided Berdych and got Nadal instead
And while Nadal wasn't 100%, make me a list of players in that draw who were arguably stronger opponents than this 'injured' Nadal. If not for Del Potro, odds are Nadal would have ended up winning the tournament anyway. Under no circumstances would anyone ever prefer Nadal over Berdych in a Slam semi.
