Golding is Britain's only representative in the tennis event in Singapore
Great Britain's Oliver Golding made a superb start to his campaign at the first Youth Olympic Games in Singapore with victory over the top seed.
The 16-year-old Londoner beat the world number one and Wimbledon boys' champion Marton Fucsovics of Hungary 7-5 6-3 in round one.
Golding, who reached the semi-finals at Wimbledon, is currently 30th in the junior world rankings.
"It's one of the best feelings I've had in my life," said Golding.
"It's only the first match though and I've got four more to win if I want to get that gold medal, which would be unreal.
"I tried to play my game and focus on what I do best. I felt like if I did that well I would stand a great chance of winning and that's what I did.
"I feel great; the last couple of months have been absolutely brilliant for me so I just want to keep that going.
"Winning with an ace was exactly what I wanted to do. I think I've got a great chance of winning the gold medal if I take each game as it comes and carry on playing like I did tonight."
Golding will play either Galeano of Paraguay or Colella of Italy in the second round.
On Monday, Golding teamed up with Czech Jiri Vesely to defeat China's Bowen Ouyang and Chuhan Wang 6-3 3-6 (10-6) in the doubles.
Team GB has 39 athletes competing in 16 Olympic sports at the Games.
