So this edition of the ATP World Tour Finals was supposed to be remembered as the moment when all those predictions of a changing of the guard came to pass, eh?
Not so fast, bub.
True, five of the nine players (we’re including Pablo Carreno Busta, who stepped in to replace injured Rafael Nadal) were World Tour Finals newbies. Six of the nine were 26 years old or younger. Grigor Dimitrov, a semifinalist in London, has patiently borne the nickname “Baby Fed” since he was a teenager, waiting for this moment to come.
