That is understandable given her long time away from the sport, but Amanda Anisimova would look to exploit any weakness with her flat, penetrating groundstrokes.Anisimova thrives from the back of the court, so we can expect Andreescu to employ a lot of low slices and invite the American forward. The Canadian does have quite a few tricks up her sleeve which could help push Anisimova out of her comfort zone.Anisimova might fancy her chances of causing an upset on Sunday if her big-hitting game is on, but Andreescu's all-court craft will likely halt the American’s charge.Prediction: Bianca Andreescu to win in three sets.
