Joao Fonseca is again spearheading the youth revolution at Roland Garros, following up his sensational triumph over Novak Djokovic by downing two-time finalist Casper Ruud to propel himself into the French Open quarter-finals.
But the brilliant boy from Brazil is not the only teen shaking up the old order, with Rafael Jodar, born just a month later than Fonseca, ensuring there'll be two precociously impressive 19-year-olds in the last-eight after his magnificent comeback triumph over experienced Spanish compatriot Pablo Carreno Busta.
In another thrilling late-night contest on Court Philippe Chatrier on Sunday, Fonseca was, if anything, even more spectacular than in his changing-of-the-guard ousting of Djokovic as he had to repel the doughty Norwegian's rearguard action before prevailing 7-5 7-6 (10-8) 5-7 6-2 after midnight.
