Edmund pulls out of Paris with injury. Undoubtedly a breakthrough year, but needs to back it up, and has a lot of points to defend in Australia.
Although it's been a good year for a number of younger players, it looks like the year end in London will have only one player, Zverev, under 25. And though he has had a great year, as yet it still looks as if he hasn't quite been consistent enough, especially in Slams, to be seen as part of the elite. Next year needs to see him, along with Tsitsipas, Tiafoe, and De Minaur amongst others, get to finals in slams, and look to be consistently ranked in the top ten, and top 3 for Zverev to have a new generation of stars.
