I didn't see Mmoh's match, but he lost to Gilles Muller. Why is Tiafoe a "funny black guy?" I'm not trying to give you a hard time, but I'm a fan of Tiafoe, so I wonder why you characterize him that way. Is it really the main feature of him and Mmoh that they're black? I don't know Mmoh's game, but Tiafoe has been making real strides of late. He has a power game, good serve (which is very US, generally, not just African American.) And he's learned to rein his emotions in, of late, and play the big points. He's still only 20. Big promise for US tennis. His win today over Verdasco was not completely unpredictable, but a great stride ahead.
