Nice way of phrasing it Litotes
Still weird that he won only 3 matches in a Slam, first time since Kuerten beat him in 2004 FO, over 8 years ago.
Hopefully he picks it up again and can still get that YE#1, but it'll be difficult if Djokovic wins the US Open.
I agree, to get YE#1 he'll most probably need help here. Ideally from Del Potro, as that would leave Djokovic very close in the race. But Djokovic is the favourite, so any help can not be counted on, we'll just take it as a bonus if it happens.
