LAUSANNE, Switzerland — 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.

CAS said the unanimous ruling goes into effect immediately.

"I am ecstatic," Pistorius told reporters in Milan, Italy. "When I found out, I cried."
