Athletics-US retain women's 4x400 metres relay title at World Championships

The United States retained their 4x400 metres women’s relay World Championships title on Sunday, finishing well clear of Jamaica and Britain.

Talitha Diggs got the Americans off to a solid start and they maintained the lead through a series of clean changeovers, as anchor Sydney McLaughlin, who shattered the 400m hurdles world record on Friday, brought it home for gold.
