Friday was a good day for Jamaicans relay teams as the men's 4x100m team won their heat comfortably at the London Olympics on Friday.
The quartet of Nesta Carter, Michael Frater, Yohan Blake and Kemar Bailey-Cole stopped the clock at 37.39 a season's best.
The finals team will see defending double Olympic sprint champion Usain Bolt replace Bailey-Cole to anchor the Jamaican team that is not just hunting gold but the possibly seeking to lower the Olympic record they set four years ago in Beijing to claim gold.
Heat 2 was won by a hard running US team that was missing 100m finalists Tyson Gay and Ryan Bailey.
100m bronze medalist Justin Gatlin anchored the US team to a national record of 37.38.
This sets up the prospect of a stellar showdown on Saturday between Jamaica and the United States.
This rivalry has gone in favour to the caribbean nation who would swept the sprints for both men and women if Allyson Felix had not grabbed gold in the women's 200m to spoil the script.
Seeking redemption the American men's quartet has vowed to get gold, but they would be hard-pressed to back up that boast with a Jamaican quartet completed by Usain Bolt,who has dominated the London Games as he did in Bejing four years prior.
Following the precedent set at last year's World Championships in Daegu, it is 4x100m and not the 4X400m that will close out the track spectacle of the Oylmpics.
Many have argued that this break in tradition by the International Olympics Committe the IOC is influenced by the super-star pull of Usain Bolt to literally 'close the show.
