Gauff is projected to rank 89th on Monday, although that will rise should she progress to the final.

Gauff secures first win against top-10 opponent when sinking Bertens

The American, who reached the second week at Wimbledon earlier this year, is now just two wins away from her first-ever WTA title having made her debut on Tour in March at the Miami Open.
She only qualified for this week’s tournament as a lucky loser after a late withdrawal from Maria Sakkari, but she now faces Andrea Petkovic for a place in the final.

Petkovic needed just over an hour to beat Viktoria Kuzmova 6-4 6-1 earlier on Friday.
Meanwhile, Jelena Ostapenko's impressive run continued as she beat Elena Rybakina 7-5 6-1.
She faces Ekaterina Alexandrova, who brushed Kristina Mladenovich aside 6-2 6-4 to reach the semi-finals.
