Superb post. Congrats to Rafa and Marc for capturing the men's doubles gold.
Rafa can obviously win these kinds of doubles titles with his level of fitness given the right partner and opposition, since he only has to cover half the court. Not sure what good it does for his single's game...
Rafa hadn't played since withdrawing at Roland Garros, Perhaps he would have done better to skip Madrid or Rome, and come into Paris in better shape since the wrist was a known problem since Miami. But he didn't and left RG on the table, and Wimbledon and Toronto thereafter, skipping both, resting body and mind with various activities, and then returning to the courts with some relatively light practice.
But in this Olympics, he took a gamble playing considering his lack of preparation and fitness, and has gradually played himself into fair form, especially on his backhand wing, so who knows? He shows a passion for the Olympics that has seemed lacking in other tournaments. He still returns short and the forehand is error prone, but if he positions himself more centrally and relies on his bh wing, he doesn't have to cover as much court.
Del Potro is still in dubious condition. He has won some matches against top players at a high level, but is he fit to go the distance in a tournament? He played very sparingly this season as he is playing not to risk that left wrist again relying on a fairly good serve and tremendous forehand to compensate for his backhand. He is still playing slice predominantly off his bh wing, and as we know, Rafa is quite good against the slice. They both played tough matches yesterday, and we don't know their condition today, but I would give a slight edge to Rafa, The Argentine Assassin's serve and forehand will have to be on fire to have a chance, and he is not fresh like he was at the start of the tournament where he ambushed the Serbian Slayer.
Anyway, I don't think either player can take the singles gold without a lot of help and hopefully neither makes their wrist condition worse in the effort. I'm not sure either will play next week in Cincinnati. But the US Open looms in two weeks and their fitness will be put to the test.
Thereafter it might not be a bad idea for them both to pretty much shut it down for the rest of the year, and work on getting 100% fit for 2017. It might be their most important year.
Respectfully,
