isn't/wasn't top notch ? yeah, right. It was pathetic. it just took Nadal playing well to put up that stream. not the tennis of his life.
That's because federer is 36.5, nearing 37 to be more precise, ¬ playing on clay as a result, Djokovic is woefully out of form, Murray out injured, Stan out injured etc.
Of course you are not going to get Nadal vulnerable unless you ask questions. No doubt Thiem is good on clay and can definitely do more than that. Which is why he won.
Doesn't mean others couldn't get a set vs an off-form Nadal like yesterday (to actually seal the deal by winning is a step further though). Someone like a Fognini playing like he did when he got Nadal twice on clay in 15, Isner serving out his mind, an in-form delpo are possibilities.
quite a few players have better game and potential outside of clay than Thiem does, right now.
if we're talking about potential, IMO : Zverev, Kyrgios, Chung, Shapo, Rublev, Khachanov ...these guys have more potential outside of clay.
