Re: Sloane Stephens or Madison Keys?
They're a bit like Wozniacki/Kvitova.
Wozniacki had the better earlier results but Kvitova caught up and became greater.
The same thing will happen with Sloane and Keys I reckon.
along with venus, na, hsieh, date-krumm, jovanovski
makarova, dokic, diatchenko, goerges and kvitova
