Based on what? Kei is clearly the more talented player of two, serving is basically the only thing Milos does better. And while Kei will never serve like Milos or even remotely, his serve does have margin to improve.The sooner these two are in the top 10 the better tennis will be. They're legit top 10 quality unlike the likes of Mugaco and Scrubcki. Despite the result I think Milos will go higher.
