Remember her? Martina Hingis turned 29 Wednesday, but that was not the biggest reason to celebrate. Her two-year ban for a positive cocaine test following the 2007 Wimbledon lapsed, and the former No. 1 is eligible to play again. In an interview with SI.com, though, she did not sound like she was ready for a comeback: "I'll leave it Justine [Henin]! It's not so easy. You need to commit. You can't just do it when you want to."
