That was why Federer was stunned. Having spent his entire adult life consciously molding himself into one of the best high-stakes tennis players in history, he'd just been beaten by an almost random sequence of events. Djokovic's snapped return happened to land in bounds; the crowd happened to set something off in Djokovic's head; this happened to inspire him to play better tennis. "I had it," Federer said about the match. "There's no more I could do. He snaps one shot, and then the whole thing changes. … To lose against someone like that, it's very disappointing, because you feel like he was mentally out of it already. Just gets the lucky shot at the end and off you go." - Christopher Chung

Such a good summary of what happened. I was totally bummed and just pushed tennis out of my mind after that match (though I did catch Djokovic thumping Nadal in the first set of the men's finals). In particular it's wishing that luck at the infinitesimal level would go Federer's way a couple times more: "Think about it: Djokovic goes from being a very good player whose season was tarnished by his inability to beat Federer (in the French Open semis and here) to holding three Grand Slam titles at once while being well on his way to completing maybe the best season in tennis history. Federer goes from being a player who can still beat the best to a definitively past-his-prime ex-champion who's dropped two straight semifinals late-round matches in majors after winning the first two sets. Nadal goes from having yet another crack at his rivalry with Federer to losing to Djokovic for a legacy-unsettling sixth straight time in a final. All because of that one shot." - Dan Hsiao
