Megan Keith was the sole Scottish representative in the women’s 10,000m after McColgan dropped out.
Despite a swell of cheers from the crowd at every pass, the Inverness runner was unable to replicate the iconic 2022 performance of her compatriot, finishing ninth in a time of 32:22.11.
Canada’s formidable Olympic hammer champion Ethan Katzberg drew gasps of awe from the Glasgow crowd with his herculean throw of 80.97m, which set a Commonwealth record.
But the biggest cheers in the hammer were reserved for Scotland’s Chris Bennett, competing in his fourth and final Games.
He finished fifth with his longest throw of 69.48m, clearly emotional as he wrapped up a 24-year career.
Alexander Thomson – who trains just down the road at Victoria Park and had fought back from knee surgery – finished ninth in the T38 100m final.
Jemma Reekie comfortably booked her place in the semi-finals of the 800m, finishing second in her heat with a time of 2:03.09 behind England’s world indoor 1,500m champion Georgia Hunter Bell.
Erin Wallace also booked her place in the semi-finals with a time of 2:03.15, but Mena Scatchard just missed out on qualification by 0.06 seconds after finishing fourth in her heat.
In the early sessions, Stephen Mackenzie got Scotland off to a strong start as he progressed to the men’s long jump final on Wednesday.
A second-round leap of 7.75m was enough to see him through in eighth place.
Meanwhile, hammer thrower Angela McAuslan-Kelly progressed to the women’s final, with a throw of 60.59m in the first round securing her place.
