In the pool, the golden tally rose to seven for Scotland in two days as Dan Wallace from Edinburgh came from behind to snatch the 400m individual medley crown.
The 21-year-old anthropology student, nicknamed Starshark, survived a tough test of his character in the 400m individual medley final but passed with flying colours as he stormed past rival Thomas Fraser-Holmes in the final 50 metres.
The Australian had already snatched the 200m freestyle title from Wallace's compatriot Robbie Renwick earlier in the night but he restored national pride as he gobbled up Fraser-Holmes' lead in the final stretch.
Wallace bellowed 'for freedom!' after touching home to claim Scotland's third pool gold of Glasgow 2014.
It was a moment of redemption for the University of Florida student, who feared at one point this year that he would be axed from Team Scotland after he was arrested in the US for urinating on a police car and suspended by his American swim team.
He said: "I just yelled at the top of my lungs for freedom because being here, the home crowd has really brought out the Braveheart and Scot inside of me and I just soaked up the moment."
In judo, 37-year-old Sarah Clark - a former European champion who won silver when judo was last in the Commonwealth Games at Manchester 2002 - showed no mercy as she quickly delivered victory with an armlock submission. It was the third judo gold for Scotland following the Renicks sisters' success at the SECC venue on Thursday.
Earlier, Team Scotland recorded their first cycling gold in the Sir Chris Hoy Velodrome as para-cyclist Neil Fachie and pilot Craig MacLean won the 1,000 metres time trial B2 tandem.
Partially-sighted Fachie and partner MacLean were the last of five teams to go and, roared on by a capacity crowd including Hoy and comedian Billy Connolly, the pair powered to victory in one minute 2.096 seconds.
As the pair completed their lap of honour around the track, Fachie unfurled a Saltire and held it aloft - seemingly hoisting it in the direction of the man who gave the Velodrome his name, with Hoy clapping his approval from a television gantry.
Louise Martin, chairwoman of sportscotland, said: "It was absolutely fantastic to see Neil and Craig secure gold. The atmosphere in the Sir Chris Hoy Velodrome was electric and I'm sure the roar of the home crowd gave them an extra edge in the final.
"I was delighted to be able to present them with their medals and they will now be aiming to come back tomorrow in the sprint event and claim another spot on the podium."
There were also bronzes for Corrie Scott, in the 50m butterfly, and Sally Conway in the -70kg judo class.
The Friday haul kept Scotland third in the medal table, behind England and Australia, with seven gold, three silver, and five bronzes.
