Lertcheewakarn, the fourth seed and the runner-up to Britain's Laura Robson at last year's Wimbledon girls' final, is said to have been shaped in the mould of Monica Seles and Marion Bartoli.
According to the Wimbledon official website, Lertcheewakarn uses double-handed ground strokes on both sides and has the ability to return serve effectively and draw her opponents into long energy-sapping rallies.
With this win, Lertcheewakarn becomes the first Thai to win the Junior Wimbledon title.
"I spoke to my parents and they are very happy. I can't wait to get back to Thailand."In the boy's singles final, Russia's Andrey Kuznetsov defeated American Jordan Cox in the boy's final match 4-6, 6-2, 6-2.
"But first I want to do some shopping here, and go to Wimbledon Village."
"Mladenovic is a very good player and is qualifying for senior events like me so its great to have won today."
"Last year I was just excited to be in the final, I never expected to get there. This year I just wanted to win as it is my last year in the juniors."
Just in case you want to know, Andrey is not related to Svetlana Kuznetsova.
