She suffered a third-round defeat at the French Open when she returned as defending champion. She had lost early at Wimbledon in two of the last three years. And she was in trouble today. “I’m happy and proud of myself. Solana played a great match. It was a tug of war. She hit some great shots. I’m happy with my serve, it held up in the tiebreaker. “I was reminding myself, remember who you are. When she served for the match I remembered that I was a great returner as well. When I served, I was focused on being aggressive and getting a high percentage in. I was relaxed, even though I was nervous. I was positive, and I think that showed.”(PA)Jamie Braidwood1 July 2026 17:29Coco Gauff wins!An ace down the T seals the deal! That was quite the encounter.
