Usain Bolt cruised to a win in his 100-meter heat at the Rio Games on Saturday, his first official action of these Olympics.

Apparently, one of the last items on Bolt's Olympic-preparation list was to get a haircut _ and Jamaica's Olympic officials tweeted out imagery on Saturday to show that he's all set in that regard.
