There haven't been any men's singles grand slam champions in a long time and Frances Tiafoe doesn't think it has anything to do with flags. For him, it's simple because Nadal, Djokovic and Federer have been too good in recent times. He was asked recently in Washington and he said:
Yeah, again, that question is asked so much. It's like I don't think it's a flag issue. I think it's a Novak, Rafa, Federer issue. You know, I mean, I think they are a big problem for everyone. I think we are all playing some great tennis. It's only a matter of time. I mean, draws are opening up more and more. You know, I mean, I see someone making semi, final, maybe winning one next couple of years. Why not?"
Tiafoe is currently experiencing a solid run in Washington hoping to take himself further and compete for the trophy.
