England has surprisingly ruled the Commonwealth Games sprint relays, with Jamaica's failure to grab gold prompting Usain Bolt to question his retirement.
England collected gold in the men's and women's 4x100m relays on Saturday, the penultimate day of competition at the Gold Coast Games.
Jamaica's men's relay team finished third; their countrywomen second - the traditional sprint superpowers ended the Games without a victory in the six sprint finals on the Gold Coast.
After watching Jamaica's fall from grace, Bolt queried his decision to give athletics away.
"Did I retire too soon? Hmmm," Bolt tweeted.
"Watching the relay just now made me ask myself a few questions."

In the men's 4x100m relay, Englishman Harry Aikines-Aryeetey held off South Africa's 100m Commonwealth champ Akani Simbine and Jamaica's Yohan Blake to secure the gold.
"I ran like a rabbit," Aikines-Aryeetey said.
"I knew I had the second fastest man of all time behind me, Yohan Blake, and the 100m Commonwealth champion behind me.
"I stayed focused and aimed for the line."
Jamaica's 4x400m women's relay team made some amends with victory ahead of Nigeria and Botswana, with Botswana winning gold in the men's 4x400m.
The relays came after Kenya's 1500m world champion Elijah Manangoi added a Commonwealth Games gold medal to his collection on Saturday.
Manangoi again pipped his countryman, silver medallist Timothy Cheruiyot, in a repeat of last year's world title result.
"A (gold) medal is so nice, so sweet," Manangoi said.
Kenya also achieved a gold-silver double in the women's 5000m with Hellen Obiri finishing ahead of Margaret Chelimo Kipkemboi.
"It's fantastic for us," Obiri said.
"We have done our best and we won gold in the (men's) 1500m as well."
