This is an interesting question I have seen in YouTube. At first glance he seems to be fast court player, pretty compact on is strokes and plays close to the baseline. And yet some say the combination of poor returning and more time on BH makes clay his current best. He's good on HC for sure, but he has a better win rate on clay on tour. He had SF in RG last year, and a Final in Madrid. I don't think he's gonna be as good Domi, Nadal, Djokovic or even Sascha here, but he could arugrably 5th best the moment. He also moves pretty well here, as he does on other surfaces.
