General Hercules, Roger Federer plays doubles with Marco Chiudinelli against Seppi/Emmrich tomorrow, then singles on Thursday along with Rafa as you mentioned...
Dr. Ivo Karlovic looked very good taking down the Colonel, #6 seed Mikhail Youzhny, last year's Halle finalist. Dr. Ivo is set to meet Federer in the quarterfinals if they both get that far. Karlovic is always a good indicator of where one's return is on grass.
Robin Haase took out the 5th seed Richard Gasquet in the other upset today.
Monfils took out Benjamin Becker to move on to face Nishikori next.
Respectfully,
masterclass
