The Swans were beaten 3-1 at non-league Salisbury City on Tuesday in their second Football Combination match of the campaign.
It follows on from the opening day reverse at Cheltenham (0-4) and last Wednesday's Combination Cup defeat at the hands of Reading (0-3).
A young Swansea City side dominated early on and had plenty of chances before finally taking lead, Matthew Wright lifting the ball over the on rushing goalkeeper. But Salisbury levelled just before half-time as Charlie Griffin's shot was parried by Rhys Wilson into the path of Robbie Matthews who placed the ball into the back of the net.
Griffin turned goalscorer when he put The Whites ahead on 59 minutes while Danny Young made the game safe four minutes later.
Colin Pascoe's side now sit bottom of the South West & Wales division of the Combination with a goal difference of minus six.
