I didnt like Stephens at -200 when this line was released but now that its gone down to -160, I think there is some good value here. Both players have good pace and power but I think Stephens is a tadbit more consistent than Hampton. Make no mistake, Hampton will be going for a lot of winners today and I think that will be her mistake. The new Sloane Stephens has developed more consistency and develops points much better than Hampton's crush it to oblivion style.
I'm going against the steam here and taking Stephens.....best of luck.
