Both the United States and Jamaica have successfully qualified for the men's 4x100-meter relay final scheduled for Saturday at the 2012 London Games.
The Americans won their heat in a time of 37.38 seconds, but the Jamaicans weren't far behind in theirs, winning in 37.39 despite lacking Usain Bolt, who will likely make a massive difference in the finals.
The Jamaicans, led by the world's fastest man in Bolt, are the defending gold medalists in the event. Jamaica set a world record in the men's 4x100 relay in Beijing four years ago, finishing in a time of 37.10.
The Jamaicans have since gotten faster, beating their 2008 time last September, setting the current world record at 37.04.
Which nation will win gold in the men's 4x100?
What It Means
Jamaica is likely on its way to a second consecutive gold medal in the men's 4x100 relay after qualifying for the final on Friday. The Jamaicans boast the two fastest sprinters in the world in Usain Bolt and Yohan Blake and thrive on the sort of electric environment that will be present around the track on Saturday.
Although Jamaica are the heavy favorites now to take gold in the event, the United States will have a real shot at winning silver and should at the very least land on the podium. The Americans boast the second-best time (only to Jamaica) this season in the event.
What Happens Next
Both the United States and Jamaica will square off against each other in the thrilling relay event on Saturday afternoon in London, which will undoubtedly have fans on the edge of their seats all the way up until the finish.
The United States has not won a medal in the men's 4x100 relay since Athens in 2004 and has not won gold in the event since the Sydney Games in 2000. Both teams will be determined to prove themselves this weekend, as the athletes look to wrap up their 2012 Olympics on a high note.
