Fed- Tsonga is more of a ratings draw...alot of people have never heard of Chardy!
In terms of competitiveness Its difficult to say which match will win there also, Jo has put on some wonderful entertaining performances in slams, he likes a big stage. could challenge even win tbf.
Chardy has played great stuff all week and has beaten Andy before so again could be really competitive. I can't see andy making the same mistakes twice though, he was caught off guard in Cinci.
So I hope Andy plays later in the day 3 straight sets...and on his way. Fed and Jo play at night 5 long greulling sets. that'll do me
