BJ King Thinks Hingis is Preparing a Tour Comeback Attempt

Billie Jean King suspects that Martina Hingis’s purpose in playing WorldTeam Tennis next month is that she is "testing the waters" for a comeback to the Tour.

That would make a third comeback, following her original retirement. The first comeback lasted just one match when she was beaten by Marlene Weingartner in Pattaya, and the second ended in disgrace when she received a two year ban after testing positive for cocaine. In fact, her game was fading badly at that stage, anyway, and she was unlikely to have continued playing beyond the 2007 season.
Hingis will play 14 matches for the New York Buzz, and she is also scheduled to partner Anna Kournikova, with whom she won she Australian Open titles, in an invitational event at Wimbledon.
