Llantwit Major are into the second round of the Welsh Blood Service Cup following a 1-0 win at Trethomas Bluebirds on Friday night.
It also marked Major's first competitive win of the season following the return of Karl Lewis as manager.
Llantwit's latest signing - ex-Merthyr and Pontypridd striker Tom Stokes - was denied a second goal in two goals on the stroke of half time, when his penalty was saved by Bluebirds keeper Sulemaine Susso.
But the visitors managed to break the deadlock on 65 minutes when Connor Goldsworthy struck for the second time since his return to Major, with Stokes providing the assist.
Trethomas boss Paul Evans was sent to the stand in the closing minutes as Llantwit held out for a first round victory with keeper Ryley Allen maintaining his first clean sheet of the campaign.
The two sides meet again - this time at Windmill Lane - when the league campaign resumes next Saturday.
