Double-amputee sprinter Oscar Pistorius won his appeal Friday and can compete for a place in the Beijing Olympics. The Court of Arbitration for Sport ruled that the 21-year-old South African is eligible to race against able-bodied athletes, overturning a ban imposed by the International Association of Athletics Federations. The court said the unanimous ruling goes into effect immediately.

"I am ecstatic," Pistorius told reporters in Milan, Italy. "When I found out, I cried. It is a battle that has been going on for far too long. It's a great day for sport. I think this day is going to go down in history for the equality of disabled people."

Pistorius still must reach a qualifying time to run in the individual 400 meters at the Aug. 8-24 Beijing Games. However, he can be picked for the South African relay squad without qualifying. That relay squad has not yet qualified for the Olympics.

Pistorius appealed to CAS, world sport's highest tribunal, to overturn a Jan. 14 ruling by the IAAF that banned him from competing. The IAAF said his carbon fiber blades give him a mechanical advantage.
