Federer v Coric
Djokovic v Zverev
Federer, at 37, taking-on the THBH society: Medvedev (win), Bautista Agut (win), Nishikori (win), Coric (Djoker Jr.), Djoker (Guówáng).
These last one or two will be tough on the old man. Coric is a good test for a Novak match.
Novak looks bored. Zverev looks enchanting in Bo3.
All we know is this: right now Federer’s BH is better than his FH.
