2017 US Open tennis

Forums:

I'm having a good time watching, as I always do. I had no idea til this year that tennis is a huge betting sport internationally. No idea.

All USA final four on the women's side.

An amazing group of women! I'm looking forward to tomorrow's semis.

The del Potro/Federer quarter just now was good - del Potro didn't stop playing til the end.

I wonder if Federer is planning to announce something like retirement? Something was occupying at least a sliver of his mind.

It might be time for people like Federer and Venus Williams to retire.

It looks like there are a lot of talented young players. 

I'm disappointed that I missed tonights matches (I know the results) and will likely miss tomorrow. I will catch the finals, for sure.

You're right, cb, it might be time...

Why would Federer retire after winning two majors?

I don't think he will, or that he should, I just wondered if that was what was on his mind. He looked preoccupied in that Del Potro match.

cb, what were you thinking?
