Defending Olympic Men's 100 Meter champion Usain Bolt of Jamaica won the competition again Sunday at the London Games, joining USA's Carl Lewis as the only men to win gold medal in the 100 in back-to-back Olympics.
Bolt previously won the gold in the 100 at the 2008 games in Beijing.
The sprinter took the gold with a time of 9.63 seconds.
Jamaica's Yohan Blake took the silver with 9.75 seconds and USA's Justin Gatlin won the bronze with a time of 9.79 seconds.
Bolt appeared pretty confident after his dominating win in the semi-final round, saying, "I'm back baby, all day, every day."
