Hingis still uncertain about future

NEW YORK -- Martina Hingis is still undecided about a return to the WTA Tour to play doubles, although she is considering teaming up with Lindsay Davenport.

Hingis also said Tuesday in a conference call from England that she will play legends doubles with former partner Anna Kournikova at Wimbledon.

Hingis is returning to play a full season of World Team Tennis this summer after a two-year ban for testing positive for cocaine in 2007. The former No. 1 player denied taking the drug but did not appeal the ban.

The 29-year-old Hingis will play 14 matches for the Albany-based New York Buzz. In early July, her team plays twice against the Washington squad led by Serena Williams and Venus Williams.
