England took both 4x100m relays to take the biggest share of relay gold, with Jamaica and Botswana splitting the 4x400m relays.
The English team of Reuben Arthur, Zharnel Hughes, Richard Kilty and Harry Aikines-Aryeetey ran 38.13 to win the men’s 4x100m from South Africa and Jamaica.
Individual gold medallist Akani Simbine pulled South Africa up from fourth to the silver medal with a storming final leg, but fell a metre short of catching Aikines-Aryeetey. For second leg runner Hughes the gold medal was some consolation for his disqualification after crossing the line first in the 200m.
Jamaica looked to have the strongest team in the women’s event, but poor changeovers between lead-out runner Christania Williams and Natasha Morrison, and then Morrison and individual 100m bronze medallist Gayon Evans, handed a winning advantage to England. Asha Philip, Dina Asher-Smith, Bianca Williams and long jump specialist Lorraine Ugen took the gold, 42.46 to 42.52, with Ugen holding off double Olympic champion Elaine Thompson on the final leg. Nigeria finished third.
Jamaica restored some normality in the women’s 4x400m in which individual medallists Anastasia Le-Roy (second leg) and Stephenie-Ann McPherson (anchor leg) teamed with Christine Day and 400m hurdles gold medallist Janieve Russell to win in 3:24.00. Nigeria was second with Botswana setting a national record of 3:26.86 in third place.
Botswana had their turn for glory by winning a physical men’s 4x400m. Leaname Maotoanong, Baboloki Thebe, Onkabetse Nkobolo and individual champion Isaac Makwala combined to win in 3:01.78 from The Bahamas, 3:01.92, and Jamaica, 3:01.97.
There was drama at the final change which led to Kenya being disqualified for moving out of order. Australia had suffered the same fate in the previous day’s heats.
