Venus, Serena’s older sister, is currently ranked at 100 worldwide in singles and is known for her fast serves. In 2011, Venus was featured in TIME magazine’s “30 Legends of Women’s Tennis: Past, Present, & Future.” As of 2012, Venus withdrew from the Australian Open to deal with Sjögren's syndrome, a disease she’s been suffering from since 2011, but plans to return to the Women’s Tennis Association during later this year.
