Former Olympic sprinter Jones signs deal with Tulsa Shock: Marion Jones hasn't lost much of her swagger.

The disgraced sprinter once called the world's fastest woman was introduced Wednesday as the newest member of the WNBA's Tulsa Shock and she offered no apologies for her steroids use or her time in federal prison. She was poised and ready for questions about her troubled past.

"The word redemption is not in my vocabulary," Jones said at a news conference, flanked by team president Steve Swetoha and coach Nolan Richardson. "I'm a competitor, I want to play against the best in the world, and I know that I will be doing that."

Her bid for a new career comes a decade after she starred at the Sydney Olympics, winning gold in the 100 meters, 200 meters and 1,600-meter relay, and bronze in the long jump and 400-meter relay. She was stripped of all five medals after admitting in 2007 that she was using performance-enhancing drugs — a designer steroid called the "clear" — at the time of the games.

Jones also spent about six months in a Texas prison for lying to federal prosecutors about doping and her role in a check-fraud scam.
