Coco Gauff sometimes feels like a tennis impostor but says the ball doesn't lie

After her Miami Open win over Belinda Bencic, Coco Gauff said she sometimes experiences imposter syndrome; she is scheduled to face Karolína Muchová in the semifinals.

Coco Gauff stood in the tunnel before the main court at the Miami Open as an announcer listed her career achievements. After her win over Belinda Bencic, she said she sometimes feels imposter syndrome even with major titles to her name. She will play Karolína Muchová in the semifinals, and the match comes at a tournament that feels like home with family and friends likely in the stands. In recent months she has worked on her serve and forehand and brought in biomechanist Gavin MacMillan after a period of uneven form. Key facts: - Gauff is a two-time Grand Slam champion, an 11-time WTA title winner, and has been ranked as high as No. 2; she is listed 11th on the all-time prize money list with more than $31 million. - She beat Belinda Bencic in Miami and is set to face Karolína Muchová in the tournament semifinals. - Her 2026 record entering Miami was 15-5, and only seven women had started the year with a better record at that point. - Gauff won the French Open last June after reworking her serve and forehand, then later experienced a stretch of troubles with her serve, including an early Wimbledon exit and difficulties at the U.S. Open. She has since worked with biomechanist Gavin MacMillan. - Matches in recent events have shown moments of tactical adjustment, physical endurance, and periods where she struggled with second-serve points and double faults but still managed to win key matches. Summary: Her remarks highlight that doubt can exist alongside success, and that she is balancing confidence with ongoing technical adjustments. The immediate next step is the Miami Open semifinal against Karolína Muchová, where her form and fitness will be on display.
