<h1>Multiple Grand Slam winner and former World No. 1 Martina Hingis has joined the star-studded lineup for The Greenbrier Champions Tennis Classic, scheduled for Sept. 16-17 at The Greenbrier in White Sulphur Springs.<\/h1>\r\nHingis, winner of a combined 23 Grand Slam titles in singles, doubles and mixed doubles, replaces Ana Ivanovic who withdrew from the event for personal reasons.\r\n\r\nOne of the all-time greats, Hingis bolsters an already amazing field of players including 14-time Grand Slam champion and The Greenbrier Tennis Professional Emeritus Pete Sampras, seven-time Grand Slam champion Venus Williams and 10-time ATP titlist James Blake.\r\n\r\n\u201cI have heard wonderful things about The Greenbrier, and the opportunity to play against some of the best players of all-time is always fun,\u201d said Hingis. \u201cI am looking forward to some great tennis on the court, as well as exploring everything the resort has to offer off the court.\u201d\r\n\r\nAs a teenager, Hingis became one of the most dominant players in both singles and doubles, and today continues to be a force in the WTA as a doubles specialist.\r\n\r\nA former World No. 1 in both singles and doubles, Hingis has won 43 career WTA singles and 60 career WTA doubles titles.
