Posted by Sabrina B. @gametimegirl Venus Williams pulled out of the U.S. Open shortly before her second-round match Wednesday, saying she was diagnosed with Sjogren’s Syndrome, an autoimmune disease that causes fatigue and joint pain. The 31-year-old American, the champion at Flushing Meadows in 2000 and 2001, played her first match in two months Monday, when she beat Vesna Dolonts 6-4, 6-3 in the first round. Williams was supposed to face 22nd-seeded Sabine Lisicki on Wednesday.
