Checkatrade Trophy: Newport County 1-2 Swansea City
Swansea City under-21s needed an own goal to seal victory and a second round place in the EFL Trophy.
Jay Foulston deflected the ball into his own net attempting to clear a long shot from Courtney Baker-Richardson.
Kenji Gorre had given the visitors the lead earlier in the second half from close range, before Shawn McCoulsky's equaliser gave County hope in a game delayed by 30 minutes due to traffic.
Swansea qualify from Group E with Forest Green Rovers.
