Madrid: Juan Martin Del Potro of Argentina, the world number seven, has pulled out of next week's Madrid Masters as he is still suffering from a viral infection, the tournament organisers announced on Friday.
Del Potro, a semi-finalist last year, missed this week's Portugal Open through illness and has still not recovered.
He has not played since being knocked out in the second round of the Monte Carlo Open in mid-April.
