Ostapenko won their only previous meeting. That was at Wimbledon last year and she won easily in 2 sets. That match came right at the start of Suarez Navarro’s awful run of form last season.
Suarez Navarro beat Radwanska in the last round which was a surprise. She hasn’t dropped a set so far though has a poor record in finals. She has won 1 of her last 10 finals but that doesn’t give the full picture. Last season she made 3 finals. She withdrew from one of them and played Sharapova and Serena in the other two.
Ostapenko has been in 5 finals. Only the most recent was a WTA final. That was last September and she was outplayed by Beck. For Ostapenko to win her first WTA title in a premier event is a huge ask.
I have to go with Suarez Navarro for the win but it could be close IF Ostapenko can handle the occasion.
Back Suarez Navarro if she is broken first.
