Regroup for what? He's 38. LOL
Fed played like a retard against faker and effectively ended his career. The guy just refuses to learn from his mistakes.
I have to try to be a bit optimistic by talking about a 2020 regroup
Roger still has the game to win but the mind, general consistency, and body are all obvious obstacles at this point. I like the idea of him tinkering with a new racquet. At his age you have to be willing to change things quickly when things clearly aren't working (tactics, prep, racquet, etc). And Roger has done crappy for over 1.5 years now.
Chances are he's done for good. He's definitely done for this year. And after this upcoming early USO loss Id prefer he takes the rest of the year off, but we know that won't happen.
