It sounds simple, but it is one of the aspects of this game that is most pleasing to watch. And with the great maestri of the sport, typically the Big Four of the past two decades, Djokovic is as good or better at this than any of his peers. Particularly compared to Roger Federer, who likes to close the point as quickly as possible, and does so with some of the most breathtaking, acrobatic, graceful shot-making in anyone’s memory, Djokovic is fundamentally a defensive player, who knows he will make the shot that will make his opponent make the last one — into the net or out of bounds.
