Great Britain's Joshua Sapwell is into the quarter-finals of the boys' singles at Wimbledon after defeating Peruvian Pedro Iamachkine on court 18.
The unseeded 18-year-old, from Bedfordshire, settled in quicker, breaking in the first and third games on the way to taking the first set 6-1.
Sapwell continued with powerful serves and accurate winners into the second to win the match, 6-1-6-3.
He will now face eighth seed Johan Sebastien Tatlot of France.
The Brit will be hoping to knock out a seeded player for the second time, having already seen off Brazilian third seed Orlando Luz in the first round, as well as replicating Kyle Edmund's boys' semi-final place last year.
Sapwell, whose first serves consistently hit about 120mph, raced into a 4-0 lead in the first set and only a strong recovery from unseeded Iamachkine prevented him from breaking in the fifth.
After a slight wobble in the sixth game, he broke once more, shortly after an unreachable forehand down the line.
The second set was much the same as the first, with Sapwell continuing to produce winners that Iamachkine could do nothing about and breaking in the fourth game.
