But while Kontaveit might be the favorite entering the match, there is a good chance it goes to three sets.Both players deploy an aggressive style and have powerful groundstrokes, so we could see a great deal of winners from each. But the Estonian has the edge with the serve; that is one area of the game Jelena Ostapenko has struggled with throughout her career.Ostapenko is always a dangerous opponent given her pure ball-striking and ability to take the racket out of the opponent's hands. But Kontaveit's recent good form and confidence should be enough to help her reach the 14th WTA final of her career.Prediction: Anett Kontaveit to win in three sets.
