Oscar Pistorius made Olympic history simply by competing in a 400-meter heat today, and he earned a chance to make some more tomorrow. The 25-year-old South African became the first amputee to compete in an Olympic race, reports the Washington Post. Pistorius, who uses a pair of carbon fiber prosthetic legs, finished second in his heat and advanced to the semifinals, notes AP. "I've worked for six years ... to get my chance," he said. "I found myself smiling in the starting block." See Bleacher Report for more on his story, including his rebuttal of accusations that the prosthetics give him an unfair advantage.
