LONDON (Reuters) - The sport's biggest name and its blue riband race combine to take centre stage for the last time on Saturday when the incomparable Usain Bolt seeks to win the World Championships 100 metres gold for the fourth time.
The Jamaican will need to start better than in Friday's heats but remains hot favourite to triumph at London Stadium in his final individual race.
