Joćo Fonseca has been a rising star for a couple of years, but today he has really come of age. The 19-year-old has now reached the fourth round at a Grand Slam for the first time in what is just his sixth major. He's the first Brazilian man to reach that stage since Thomaz Bellucci at the 2010 French Open.
And after today's performance, some will be wondering if he can emulate Brazilian icon, Guga Kuerten, by even lifting the title.
