Sierra has the stroke-making ability to trouble some of the top players. However, she lacks the finishing punch to win cheap points. On the other hand, Boulter is an expert at winning baseline exchanges and spreading out the dimensions of the court. While her weakness lies in her ability to handle the net game, the Brit should prevail in this Round of 64 over an inexperienced opponent.

Prediction: Katie Boulter in straight sets.
