Really Williams should beat Kerber if she doesn't tighten up... but we've seen it happen a few times recently in finals... If Kerber keeps it close in the first set... it could be another shock. Not one I'd bet on, but I did pick Kerber in the poll even though SW should really win.
Good going @Bert. I'm on $10 again... Did well until the last couple of days when I lost around $40 on Fed and the Euros.... everything else went pretty well!
