Kei will play and exo against Haas on May 22!
So no ATP tournament next week.
Maybe it's better for him to test his form in a relaxed atmosphere of an exo against a player he knows well?
Other participants of the three-day exhibition tournament are Nadal, Federer, Djokovic, Wawtinka, Blake, Monfils, Safin, PHM, Clement, Benneteau and Baghdatis.
Nalbandian was originally going to play but he had a hip surgery this week, so I guess Kei is his replacement.
In another news, Japan Open finally secured a major sponsor after AIG understandably ceased the contract at the end of last year.
New main sponsor is major Internet shopping mall operator Rakuten.
