Martina Hingis to play WTT

Martina Hingis can't help but contemplate yet another comeback when she sees the success Kim Clijsters and Justine Henin are having after being away from tennis.“There's a spark,” Hingis said in a telephone interview with The Associated Press.But she also said she would rule out the possibility of a return to the tour “at this point,” primarily because of all the travel.
The five-time Grand Slam singles champion and youngest woman to be ranked No. 1 retired for the second time in 2007, when she was given a two-year suspension for testing positive for cocaine. Hingis denied taking the drug but did not appeal the ruling.
That ban ended Sept. 30, and the 29-year-old Hingis is eager to get the chance to play more tennis this year: She has committed to a full season of World TeamTennis, the coed league founded by Billie Jean King and heading into its 35th season.
