PHILADELPHIA, United States — Jamaican women won two events and the 4x400m men created a mild upset in the USA vs The World series on the final day of the 123rd Penn Relays Carnival at Franklin Field on the campus of the University of Pennsylvania.

Under bright blue skies, the Jamaicans cheered on by a predominantly Caribbean crowd, continued their good run from last weekend’s IAAF World Relays Championships in the Bahamas.

The Elaine Thompson-led women’s 4x100m team won in a season’s best 42.25 seconds, faster than the winning time in the Bahamas; the women 4x400m held on to beat the USA while a strong run from Olympic semi-finalist Fitzroy Dunkley saw the Jamaicans just edging the USA on the line in the men’s 4x400m.

Thompson got the baton just a few steps behind the USA Red’s English Gardner and got by her after a few strides then ran away to easily win the 4x100m.

Christania Williams led off the team and handed off to Kerron Stewart while Gayon Evans ran the third leg.

The women’s 4x400m team showed a lot of guts and determination to keep the USA at bay, third leg runner Dawnalee Loney dug in deep to create separation before handing off to anchor leg runner Janieve Russell who kept her head despite challenge from the experienced Natasha Hastings.

Stephenie-Ann McPherson and Shericka Jackson ran the first two legs for the Jamaican girls who ran 3 minutes 28.32 seconds while the USA ran 3:29.30 seconds.

The men’s team of Jermaine Gayle, Martin Manley, Leford Green and Dunkley clocked a creditable 3:03.14 seconds to win the 4x400m for the first time since 2005.

Dunkley got the baton behind the USA’s veteran Calvin Smith and gradually closed the gap until just before the line when he passed him for the victory.

The American ran 3:30.25 seconds and the Bahamas were third in 3:06.20 seconds.
