With a slight change in the order of the runners, Elaine Thompson anchored Jamaica to what was an easy win in the 4×200-metre final at the IAAF/BTC World Relays in Nassau, Bahamas.
Running out of lane 6, the Jamaicans were given a flying start from Jura Levy, who put the team in front, a lead that would never be relinquished.
Shericka Jackson’s second leg was also very impressive, the tall powerfully built 400-metre runner outclassing her opponents, before Sashalee Forbes’ leg proved there would be no contest.
Thompson’s anchor was nothing more than a stretch of her legs, the fastest woman in the world over 200 metres facing no challenge except for the clock.
She beat that clock too, the race ending in a World Relays record, 1:29.04.
The United States, who were expected to challenge the Jamaicans, were beaten into third by a dangerous looking German team, finishing in 1:30.68 seconds.
The United States team stopped the clock in 1:30.87.
Trinidad and Tobago finished just outside of the medals, though a long way back in 1:32.63, while the other Caribbean team in the finals, the British Virgin Islands were seventh in 1:35.35.
