Brazilian rising star Joao Fonseca showcased his title credentials by grinding out a four-set victory over two-time finalist Casper Ruud to book his place in the French Open quarter-finals.
The 19-year-old, who had fought back from two sets down to win his previous two matches, proved his coming-of-age third-round win over Novak Djokovic was no fluke by overpowering the 15th seed to win a bruising match 7-5 7-6 (10-8) 5-7 6-2.
It capped off another astonishing day in Paris where the next generation made their mark, with Fonseca's fellow 19-year-old Rafael Jodar and Czech Jakub Mensik, 20, also reaching the last eight at a major for the first time.
