And it's over. Nishikori clearly injured, down 3-0 , has retired. A real shame for him, he was playing so well. Well, that's the story of his career also. He does get injured a lot, though he has been better this year than most. Nadal takes Madrid.
Congratulations to Nadal and his supporters.
Commiserations to Nishikori and his fans.
Respectfully,
masterclass
