WIMBLEDON, England — The Big Three now have 20 apiece.
It is a development that would have seemed unlikely to Novak Djokovic as he made his way onto the tour in the aughts with Roger Federer and Rafael Nadal racking up Grand Slam singles titles.
Federer was entrenched at No. 1 and had found his groove after an up-and-down start. Nadal, a genuine prodigy, was already all but unbeatable on clay courts in his teens and would soon challenge Federer on every surface.
They were a duopoly, the dominant topic in men’s tennis for good reason.
