What's amazing is that Isner has faced 126 BP's this season and saved 72% of them, Milos 83 saved 76%.
Milos has won 4% more serve games, so I'd still probably say he has the edge, but it's very close, I'll give you that.
Actually Isner's clay return stats are worse than his hard I just found.
Wait until he starts having deep runs in big tournaments - Masters and Slams - his stats will then become normal. Isner managed to serve the likes of Federer and Djokovic off the court, but that obviously has a negative impact on his stats.
It's not really close; pretty much every pro asked said Isner has the best serve, no one even mentioned Raonic. Milos has a great serve, but Isner in a class of his own. His serve alone makes him a threat; even Federer, famed as the best returners of big serves, struggles to find answers against it.
Isner's return is abysmal everywhere. He must be one of the poorest returners ever to make it to the top 10, if not the poorest.
It's not that he couldn't get to them, it's that he couldn't hit them the way he wanted.
No, it just means that Cilic is good at returning Roddick's serve and Roddick is poor at returning.
He just needs to get to them to stop it from being an ace...
Forget Roddick if you want. He outaced all his opponents in his 2009 US Open run and 2010 AO run, all of them.
