“It’s pretty cool to win again," he said. “It was pretty tough conditions to deal with but I managed myself well and played well in the end.

“I’m just trying to improve little things in my game, take it match by match, focus on the physical aspects and just do the best I can."

A high octane start to the match saw both Searle and Fonseca going all out with their big powerful serves and heavy groundstrokes. Coming into the contest, neither player had dropped a set so far in the tournament and it was easy to see why – with no break point in sight they fought into the tie-break.

Playing in front of the home crowd, the 17-year-old Brit raised his game to another level at a crucial moment in the match. While Fonseca’s serve deserted him in the tie-break, Searle racked up his ninth ace to crown a brilliant first set performance and edge the lead.

The Loughborough National Academy scholar continued to move through the gears in the second set and showed maturity beyond his years to channel any nervous energy into controlled aggression through his groundstrokes.

The Brazilian was able to stave off break points at the start of the set, but as Searle continued to pile on the pressure from his return, he got his result at the fifth time of asking to take a 5-3 lead. Serving for the match in the biggest match of his career to date, Searle remained cool, calm and collected and supercharged himself to the semi-finals with a hold to love.

Searle moves on to face his third seeded opponent of the tournament so far in USA’s Williams – having knocked out the world No.2 Juan Prado Angel in the first round as well. Williams won the Australian Open Boys’ doubles earlier this year and also reached the quarter-finals at Roland Garros.

Also in junior quarter-finals action today were Ranah Stoiber and Mika Stojsavljevic who both exited the Girls’ singles in three sets.

Stoiber opened up the day on Court 3 against WTA world No.348 Nikola Bartunkova – getting off to a one set lead before losing out to the Czech star 1-6, 6-1, 6-2.

The young Brit leaves Wimbledon having now reached the quarter-finals or better at three of the four Grand Slams (Australian Open, Wimbledon and the US Open).

14-year-old Stojsavljevic fought hard from a set down against fifth seed Renata Jamrichova but eventually lost 6-2, 6-7(8), 6-1.

As the youngest player in the final eight at this year’s Championships, Stojsavljevic leaves SW19 having proved herself against some of the to juniors in the world.
