[4] Rafael Nadal (ESP) vs [20] Pablo Carreno Busta (ESP) – This is a lot like Rafa’s last match.  Rafa should win against a gritty player from Spain.  Nadal is the Clay GOAT and is in excellent form in 2017, but I have to also think he is in the heads of his countrymen.  I think Nadal is 95% plus to win this match.

[1] Andy Murray (GBR) vs [8] Kei Nishikori (JPN) – Murray is playing his best clay court tennis of the season.  Nishikori is playing his best tennis of the season.  Nishikori beat Murray in the quarterfinal round of the 2016 US Open.  That has to give Nishikori some added belief.  Having said that, I think Murray has a 55-65% chance of winning this match.

[2] Novak Djokovic (SRB) vs [6] Dominic Thiem (AUT) – This will likely be closer than their recent match in Rome.  Still, I think Djokovic’s style bothers Thiem who likes to take a full swing at the ball.  Novak tends to rob Thiem of time.  That produces errors.  Thiem is not (yet?) physically able to do what Wawrinka can do and blast through the court.   I think Djokovic is a healthy 80% likely to win this match.

[3] Stan Wawrinka (SUI) vs [7] Marin Cilic (CRO) – I am going to be dull and take the top 4 seeds.  Cilic is playing his best tennis of the season.  He certainly could win this match, but Stan seems to be in his peak form and it will take an outstanding effort to eliminate him.  I think Wawrinka is 65% likely to advance.
