Olympic champion Elaine Thompson-Herah claimed her first Commonwealth Games 100m title as Daryll Neita’s challenge failed to materialise.
The 30-year-old ran in 10.95 seconds, while England’s Neita only managed bronze after a shocking start.
Jamaica’s Thompson-Herah had not previously won an individual Commonwealth Games title before despite claiming five Olympic golds.
“I feel good, I could have had a better execution but I’m still grateful to win my first Commonwealth title,” she said.
“I started as a rookie in 2014. Then I came fourth in 2018 in the 200 metres. Now I’ve moved up to a gold, so I’m grateful.
She was the only one of Jamaica’s star trio competing with world 200m champion Shericka Jackson and 100m champion Shelly-Ann Fraser-Pryce skipping the Games after last month’s world championships in Eugene.
Thompson-Herah took 100m bronze behind her teammates in Oregon and was the star name in Birmingham, with England’s Dina Asher-Smith out with a hamstring injury.
It meant Neita, who reached the Olympic final last year, was expected to be Thompson-Herah’s main rival and the British champion smashed her personal best, running 10.90 seconds in the semi-final.
But she could only run 11.07 seconds in the final after a terrible start and also finished behind St Lucia’s Julien Alfred.
“I let myself down. I want to go back, see it with my coach, analyze it, be told, beat myself up,” said Neita.
“It shows that my pick-up is phenomenal, but I can’t afford to run 10.90 in the semi and then 11.07 in the final. It’s not good enough.
“It’s frustrating because I was able to win it and I let myself down. I drive one of the fastest women of all time, the competition was high, but I could have done better.
“One thing about me is that I can turn every negative thing into a positive. I’m going to use this building for the next thing.”
In the men’s race, Kenya’s Ferdinand Omanyala took the title in 10.02 seconds ahead of defending champion Akani Simbine.
Sri Lanka’s Yupun Abeykoon took bronze while England’s Nethaneel Mitchell-Blake suffered an apparent hamstring injury and finished last.
Omanyala shook off the disappointment of last month when he ran into visa problems ahead of the world championships and only arrived in America hours before his 100m heat, before being knocked out in the semi-finals.
“I came here with the sole aim of winning the gold and in the final it was a case of controlling the race from the start,” he said.
“When I got off to a good start, I knew I wanted to win the gold. When I crossed the line I wanted to jump for joy.”
Scotland’s Eilish McColgan took gold in the 10,000 meters in a Games record 30 minutes 48.60 seconds, mirroring mum Liz who won the race in 1986 and 1990.
It was her first major title when she beat Kenya’s Irene Cheptai after a race-long duel.
She said: “It’s been an up-and-down year. But I knew that fitness was somewhere in me. Having my family here and the crowd here. It vibrated through my entire body. I just wanted to.
“I knew the Kenyans were super strong and would throw in the punches. But you can see in the last 100m I wanted gold. It is an absolute dream. It is so special to have it here in the UK.
“This is my fourth Commonwealths and I’ve come sixth every time. I was ready to win the medal.”
Earlier in the morning session, Matt Hudson-Smith eased through the first round of the 400m at Alexander Stadium.
The Wolverhampton-born athlete took bronze at the world championships in Eugene last month, winning her heat in 46.26 seconds.
