Twell's bronze in the 1500m takes Scotland's medal tally to eight
Stephanie Twell has won a bronze medal in the Commonwealth Games women's 1500m final, won by Nancy Langat of Kenya.
However, team-mate Lee McConnell, who won silver eight years ago in Manchester, had to settle for fifth place in the women's 400m.
Shooters Neil Stirton and Jonathan Hammond won bronze in the 50m rifle three-position pairs, just behind England's James Huckle and Kenny Parr.
Scotland's medal tally is now eight - one gold, two silver, five bronze.
Twell, 21, told BBC Sport: "I stayed relaxed after one of the Kenya runners put a block on me.
"I kept driving and driving during the race but felt I was going lower to the ground.
"All the encouragement I got from coach Mick Woods in the training sessions helped me."
Twell was beaten to the silver medal by New Zealand's Nikki Hamblin.
I didn't start hard enough - McConnell
The Aldershot, Farnham and District club runner added: "The Commonwealths is a big stage - it's not a lesser competition. I'm going to use this as a springboard."
McConnell, meanwhile, felt that she had paid the price for being drawn in an unfavourable lane after finishing runner-up in her heat.
"I think I was really out of it by 200m. I clearly didn't go out hard enough. I began in lane nine and made it hard for myself," said the 31-year-old.
And referring to her effort to close the gap on the race leaders in the final straight, she said: "I was trying hard but I knew I had a lot of work to do.
"I was trying to be as strong as I could but the damage was done in 0-200m."
Her race was won by Amantle Monsho from Botswana, who clinched her country's first Commonwealth gold in a Games-record time of 50.10 secs.
The Scots shooting duo finished on the same score as English rivals James Huckle and Kenny Parr.
However, they lost out on silver following the x count - an additional target within the maximum 10 target.
Stirton picked up a second Commonwealth Games medal in Delhi
India continued their excellent shooting form, with Gagan Narang and Imran Hasan Khan taking the gold medal.
It is a second success in the event for Scotland, with Jennifer McIntosh and Kay Copland winning bronze medals on Tuesday.
And Stirton adds his prize to the silver medal he received in Melbourne four years ago for the 50m rifle prone pairs.
Scotland's mixed doubles tennis pair of Colin Fleming and Jocelyn Rae are in with a chance of adding to that tally, having reached the semi-finals.
They beat the Indian second seeds Sania Mirza and Leander Paes 7-5, 6-4 in front of a capacity 5,000 crowd.
Meanwhile, illness means Caitlin McClatchey will not defend her 400m freestyle swimming title on Friday.
