LONDON (Reuters) - Teenager Coco Gauff has captivated Wimbledon with her extraordinary talent and youthful exuberance but, as her beaten opponent said on Tuesday, she is "probably older in her head than the numbers show".

The 15-year-old American exhibited remarkable maturity and poise to fight back from a set and 5-2 down in her third-round 3-6 7-6(7) 7-5 defeat of Slovenian Polona Hercog.
