Jamaica 3 USA 0

3 is the number of world records Jamaica's men set in the 100m, 200m and 4x100m relay, but perhaps I could have gone for Jamaica 4 USA 0 given that Jamaica won the men and women's 100m and 200m. The USA may point to their wins in the women and men's 4x400m relays, but then again the latter win wasn't so surprising given that they swept the individual event. It looks as if the era of US sprinting supremacy is well and truly over, roll on 2012.
