He has only lost 90 points so shoud be able to make that up at Madrid as he has nothing to defend. I feel sure that he is not 100% but, of course, will not make an excuse.
Not that it's of huge importance, but he also has 45 to defend in Barcelona where he got to the QF last year before going out to Raonic.
