Both the men's side and women's side each lost a big name on Wednesday as Sweden's Robin Soderling and American Venus Williams were forced out of action at the 2011 U.S. Open due to illness. Soderling never played in a match at the Open as he was scheduled to begin action Wednesday against Louk Sorensen of Ireland in the first round. The number six-seeded Soderling complained of headaches and cramping and was advised by the medical staff to pull out of the event.

The 31-year-old Venus, who was to take on the number 22 seed Sabine Lisicki from Germany on Wednesday, issued a statement citing Sjogren’s syndrome, an autoimmune disease that causes fatigue and joint pain, as the reason for her withdrawal. On Monday, her first match in more than two months, Serena defeated Russian Vesna Dolonts, 6-4, 6-3 to advance to face Lisicki.
