Before that, legendary player Mima Jaušovec won the French Open and Wimbledon junior titles in 1973 and 1974, respectively, before going on to win the French Open Ladies' title in 1977.

After today's victory, the 17-year-old from Hrastnik said that he had limited his phone use during the tournament in order to concentrate on his game and was, therefore, unaware of the record.

He said that winning a Grand Slam, one of the four biggest tournaments in tennis, was what every child dreamed of doing and that his achievement would probably sink in over the next few days.

He is a distant relative of footballer Benjamin Šeško, who plays for Manchester United, and today's win will allow him to enter qualification for next year's men's main draw.

This year's men's single title was won by Spain's Carlos Alcaraz, making him the youngest ever player, at just 22, to have won all four senior Grand Slam titles. He beat Serbia's Novak Djokovic by 3 sets to 1. The former world no.1 had been aiming for a record 25th Grand Slam victory.
