http://www.msnbc.msn.com/id/20287593/ 2-time major champion Mauresmo withdraws from U.S. Open NEW YORK (AP) -Two-time major champion Amelie Mauresmo pulled out of the U.S. Open on Wednesday, citing a groin injury and the need to recover fully from the appendectomy she had in March. Mauresmo hasn't played in a tournament since losing in the fourth round at Wimbledon on July 3, although she did participate in France's Fed Cup semifinal July 14-15. She put at least part of the blame for her third-round loss at the French Open in June on the groin problem. "My doctor has recommended that I allow myself additional time to rest and recover from this injury so that it is completely healed,'' Mauresmo said in a statement released by the WTA Tour. "Obviously, this is one of the worst times of the year for me to have an injury.'' Mauresmo, formerly ranked No. 1 and now No. 7, won the Australian Open and Wimbledon in 2006. She reached the quarterfinals or semifinals at the U.S. Open each of the past six years.
