As always in the last decade or so, the question before the ATP Tour Finals singles draw has been: which group will welcome two of the “Big 3”.
On Tuesday in London, the answer was revealed: the Bjorn Borg group will have No. 1 Novak Djokovic and No. 3 Roger Federer.
On the flip side, the Andre Agassi group will have Rafael Nadal – health permitting, of course.
And it also will have the big wild card on the ATP Tour during this second half of the season in Daniil Medvedev.
Here’s what the groups look like.
On difficulty, you’d have to give a slight edge to the Borg group because of the uncertainty with Nadal, and the rookie status of Medvedev (who is in his first trip to London).
At the same time, the matchups in the Agassi group, right from the first day, seem slightly more intriguing.
That, of course, is all a matter of opinion.
GROUP ANDRE AGASSI
 Rafael Nadal
 Daniil Medvedev
 Stefanos Tsitsipas
 Alexander Zverev
GROUP BJORN BORG
 Novak Djokovic
 Roger Federer
 Dominic Thiem
 Matteo Berrettini
The doubles groups – also named after notables – shook out as follows.
Group Max looks the tougher of the two. But all to be decided.
