Daniel Nestor and Kristina Mladenovic defeated top seeds Bruno Soares and Lisa Raymond

5-7, 6-2, 8-6 to win the Wimbledon mixed doubles title last night.

The 40-year-old Canadian Nestor and 20-year-old Frenchwoman Mladenovic have struck up a remarkable rapport in a short space of time: their first competitive match together was at last month's French Open, where they lost in the final.

Here, they fared better, dropping the first set before saving two match points in the third and claiming the title in a match that lasted a little over two hours. Marion Bartoli, the Wimbledon women's singles champion and a close friend of Mladenovic's, watched from the stands before heading off for the champions' ball.

It was Nestor's third grand slam mixed doubles title – each of his wins have come with a different partner – and he has also won eight major men's doubles crowns and the 2000 Olympic gold medal.

The 39-year-old Raymond could not add to her four grand slam titles in women's doubles and seven in mixed, which included last year's Wimbledon crown in partnership with compatriot Mike Bryan, who won the men's doubles title with his brother Bob on Saturday.

Meanwhile, Italy's Gianluigi Quinzi won the Wimbledon boys' singles title after a hard-fought final against South Korean Chung Hyeon.

Sixth seed Quinzi beat Englishman Kyle Edmund in the semi-finals to spoil the chances of a home finalist, and carried his impressive form into today's title match on Court One, triumphing 7-5 7-6 (7/2). In a battle of 17-year-olds, unseeded Chung dropped the opening set despite breaking serve three times.

The second set progressed in a more orthodox fashion, as both players tightened up on their serve and neither could achieve a break. The resulting tie-break was dominated by Quinzi, forgoing the need for a final set.

Previous winners of the junior title include Bjorn Borg, Ivan Lendl, Pat Cash and Roger Federer.
