Triple Olympic and World champion Usain Bolt anchored the Jamaican Gold team to stunning 37.90secs to win the USA vs World 4x100m relay.
The time was a new Penn Relays record – removing the old mark of 37.92 set last year by the Americans.
Bolt raced with Mario Forsythe, Yohan Blake and Marvin Anderson.
The Jamaicans defeated USA Blue who came home in 38.33secs, with USA Red finishing third in 38.50.
The Jamaica Black squad which included Olympic gold medallists Nesta Carter and Michael Frater were fourth in a time of 38.72.
Former world record holder Asafa Powell did not run at the carnival – to the disappointment of the many Jamaicans who came to see the top class athletes gracing the track.
