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.
