Although Cambridge lucked through to the semifinals, he was so far off peak that he looks like a question mark for the 4×100 m. There's a very good chance he'll be replaced by his Rio teammate, alternate Yoshihide Kiryu, who ran 10.05 two weeks ago at a low-key meet in Tokyo after performing poorly at the National Championships in June. With 200 m man Shota Iizuka also not looking 100% there's even a chance that Kiryu could be the only member of the Rio silver medal squad to start the relay in London.
But before that comes Saturday's 100 m semifinals and final. No Japanese man has ever made it to the final, and to get there Sani Brown or one of the others will probably have to deliver the country's first-ever sub-10 clocking. Safe to say TV viewership ratings in Japan will be on the high end for the semis.
