Suguru falls under T44 classification as he has a single, below the knee amputation.
They didn't explicitly say that, but "T44 high jump" and "T44 100 m" sound a lot better than "single amputee high jump" or "prosthetic legged 100 m."
And you get to learn about disability classifications for the upcoming paralympics!
Learning is fun.
