Including drop shots.Charlie Eccleshare: A match I watched from start to finish and wrote countless different drafts about, it has to be 19-year-old Brazilian Fonseca’s five-set win over Djokovic, a 24-time Grand Slam champion 20 years his senior.Fonseca has had to carry the burden of being hailed as the Next Big Thing for a year and a half, and this felt like the moment he showed the wider world why. The fearless forehands to reel Djokovic in from two sets up, the ability to feed off a crowd that was full of passionate Brazilians, and then the nerve at the very end to hit three straight aces to go from break point down to victory.There were shades of a 19-year-old Roger Federer beating Pete Sampras, at the time the most decorated male player in history, at Wimbledon in 2001.João Fonseca used his full repertoire of shots to defeat Novak Djokovic at the French Open. (France TV)Charlotte Harpur: Fonseca vs Djokovic.In the first two sets, Djokovic’s shot selection, execution and athleticism showed why he is one of the greatest players of all time. The 39-year-old pulled the Brazilian, an opponent practically half his age, from side to side, forwards and backwards, as if he had him on a string, crafting points like a magician. But just when Djokovic looked like the puppet master, Fonseca pulled out his own tricks. He hit the lines, found clutch drop shots and hit three consecutive sledgehammer aces to become only the second person ever to beat Djokovic from two sets down.Matthew Futterman: Fonseca vs Djokovic. It seemed so impossible that Fonseca could manage a comeback from two sets down, given that only one player had done it against Djokovic before. Djokovic even had an early break in the fifth set. Surely it was over.It was — for Djokovic. He just didn’t know it yet.Favorite match?Wallace: The Maja Chwalińska vs. Diana Shnaider women’s semifinal, which the qualifier and world No. 114 won 7-6(4) 6-4, was an absolute treat. It was so fun to watch the world No. 114’s anticipation, shotmaking and defensive capabilities slowly squeeze the will out of her seeded opponent — and Shnaider did a good job holding her own.Both players were so creative with their tennis and prepared for the moment, though they had every right to be intimidated. The fantastic atmosphere, thanks in large part to the hordes of Polish fans supporting Chwalińska on Court Philippe-Chatrier, made this a delight.
