Surrounded by so many reporters, photographers and TV cameras, Abdul Hakim Sani Brown, the latest sprint phenom from Japan, seemed a little uncomfortable.

"No, I didn't think about this," the 16-year-old said, when asked if he'd expected such a large media presence waiting for him after a practice in Tokyo on Saturday.

It was the first workout for Sani Brown since he returned from Cali, Colombia, where he dominated the track and captured a pair of gold medals in the July 15-19 IAAF World Youth Championships.
