Serena leads their previous matches 2-0. Both were last year on hard courts. She won in straight sets each time.
I expected Keys to push Muguruza hard in their semi final but also thought that she would be the one to make more errors. In fact she played an excellent match and won in straight sets.
Serena made slow starts to her first 2 matches but was too strong for Kuznetsova and the in form Begu. I doubt that Keys believes that she can beat Serena. I think the most she can hope for is to take a set. Keys’ hard hitting playing style suits Serena and she can redirect Keys’ power and use it against her.
I want a better price on Serena before backing but in reality I expect Keys to be super nervous at the start. Lay Serena if she breaks early. At least the low price lay will limit our liability.
