Yemi Mary John’s brilliant anchor leg booked Great Britain a place in Saturday evening’s 4x400m mixed relay finals as the World Athletics Championships got underway in Tokyo.
The British quartet of Lewis Davey, Nicole Yeargin, Toby Harries and John needed to finish in the top three in their heat to automatically qualify, and came second in 3:10.22 behind the United States, after John hunted down South Africa’s Zeney van Der Walt.
