On the fourth match point, Djokovic ambled in for a serve-and-volley. Pushed well off the court, Cecchinato swung his one-hander, rolling the ball right over his opponent’s head and into the back corner, and collapsed in tears. Lately the Serbian great has been giving a lot of people the best days of their lives. (His side of things looked much more like a low, as he ducked out of an unusually brief press conference in a side room and said he wasn’t sure if he’d even play the upcoming grass season.) It was just in April that Cecchinato won his first-ever title on tour, at a tournament three tiers down from the one he’s in right now. Now, improbably, it’s the second week of Roland Garros and he has to beat Dominic Thiem to make the final.
