Yes, indeed this Miami is showing signs to be one of thoses tournamets where favs get beat up.
and today there are some good choices...
no.1 Surely its Mayer. Tsonga is nowhere close to his potential at this time and Mayer had some solid matches here so I believe he can stand with the Frenchman.
no.2 Monaco! Yes, sir! Roddick did beat Fed but it can play against him today, cause he is just not one of those players who can build up on his winnings. Monaco will do a lot to put some fight today.
and yes, do not forget about Simon. This insane +5 that is on table. Murray is still serving pretty awful, so I wuldnt be very surprised if he let this one go.
Conclusion. Take all 3 dogs here to win matches and you wil be a winner at the end of the day.
