Wozniacki 1.38, Stephens 3.60
Wozniacki leads their previous matches 5-1. Their last meeting was in January last year in Auckland. Stephens won on a hard court in straight sets. Wozniacki’s last win was on grass in 2014. All their previous matches ended in straight sets.

Both have been impressive this week. Wozniacki beat Pliskova in 3 sets in the last round. I was a hard fought match with both players’ serves coming under pressure. pliskova was broken 5 times and Wozniacki 3 times in 3 sets.
Stephens has beaten Kvitova, Kerber and Safarova so far. Safarova took her to 3 sets in the last round. She put her under a lot more pressure than Kerber did in the previous round. Stephens was broken 5 times.
I expect to see a few breaks of serve. Some value on Stephens. Back Wozniacki if Stephens breaks and holds.
Update: Wozniacki won in straight sets.
