True, he does look solid on grass, but I think there may be more to him that just that surface. He ran Rublev pretty close in the Madrid masters on clay about a month back, losing in a close third set 6-2 4-6 5-7. He's also only 20, so plenty of time to improve... and he is improving all the time, this time last year he was ranked 250.
Peniston may be a bit different, as he's 26yo.
Draper is up against Schwartzman today, thats going to be a real test for him, Diego is a
real fighter but Grass is his least favourite surface. Draper is favoirite though @1.55 on Rollbit
compared to 2.41 for Diego.
On the Womens side Haddad Maia is playing again after getting past Kanepi yesterday.
She faces Burrage who is unknown to me, I'll keep backing Maia as she seems to be
holding her brilliant form.
