I think Cilic takes Simon. Simon will have a much tougher time with Cilic then he did fending off the struggling David Ferrer.
Berdych looks like he will beat Thiem. Gulbis got out to a 2-0 set lead and then started lingering around and making unforced errors and going for big shots. Berdych should be able to shut him down.
Parlay pays out even money. I think it is great value and worth a shot here.
