Britain's last hope in the junior singles at Wimbledon, Joshua Sapwell, was beaten by ninth seed Johan Sebastien Tatlot in the quarter-finals.
The Bedfordshire 18-year-old could not find the same level of performance as he had in the previous rounds.
After a tense first set without any breaks of serve, Frenchman Tatlot took the tie-break 7-5.
A deflated Sapwell was broken twice in the second, with Tatlot taking his first match point to win 7-6 (7-5) 6-1.
The defeat ended a positive Wimbledon for Sapwell, who just missed out on matching Kyle Edmund, who reached the semi-finals last year.
British boys' number four Sapwell, ranked 157 on the ITF circuit, beat third seed Orlando Luz in the first round, but began his game with Tatlot nervously as both players struggled to find their rhythm.
He saved three break points in the third game, but showed signs of frustration with the way he was playing, and despite saving one set-point in the tie-break, his French opponent capitalised on his second opportunity with an overhead smash.
Tatlot gained in confidence as a result and broke Sapwell in his first two service games, before closing out the match with one of his powerful serves, which regularly clocked 120mph.
