Clyde boss Danny Lennon heaped praise on new boy Olly McDonald after they upset Championship side Morton in Group D.
The 22-year-old striker, who joined from Lowland League Gretna 2008, bagged his first goal for the club on his first start to give them a maiden win in the Premier Sports Cup yesterday.
McDonald broke the deadlock for the League One outfit after 37 minutes with a thumping low drive that beat Brian Schwake at his near post.
And seven minutes from time Ross Cunningham sealed the points from the penalty spot after Conor Duthie's trickery in the box lured Jack Baird into making the foul.
The result helped Clyde - who also saw Jordan Allan's first half penalty saved by Schwake - bounce back from a midweek defeat to League Two Bonnyrigg Rose, and Lennon was delighted for his summer signing.
He said: "It's a fantastic finish from Olly. I thought he was a constant pain and threat during the first hour.
"He just picked the right thing to do and that is the sign of an intelligent player so I'm very pleased for him.
"For such a small guy, Olly gets himself about well and gives as good as he gets to the bigger lads.
"We gave a few players their opportunity and I'm delighted to say everyone of them took it.
"I thought there was great energy in the team and I've seen improvements from the Hibs game to the Bonnyrigg game and now this one as well."
Clyde's win was their first at their new home at New Douglas Park in Hamilton and it inflicted a first defeat of the season for Ton gaffer Dougie Imrie.
The visitors rarely threatened in the first half and it took Morton 66 minutes to get a shot on target and when Lewis McGregor fired straight at Neil Parry from 25 yards.
Robbie Muirhead headed over from close range and Cameron Blues couldn't keep his effort down 10 minutes from time.
Imrie said: "We were second best for large parts of the game and that's disappointing.
"It's going to be a rollercoaster from now until the end of the season with so many young players in the squad from the academy.
"And today was one of those days when we just weren't at it."
