Christian Norton opened the scoring early on, his third goal of the season, before further strikes from Will Ferry and Oludare Olufunwa gave Saints a comfortable cushion, and ultimately sealed maximum spoils.



Swansea pulled one back in the second half, Owen Jarrett Evans with the goal, but the visitors controlled a large percentage of the tie, and drew on much of the confidence gleaned from recent wins over Brighton and Reading.



Enzo Robise was the creator for Norton to break the deadlock in the 19th minute, whose clinical finish was indicative of Saints' first half domination.



The ball was won in midfield, and then picked up by the energetic Robise, who spotted the run in behind from Norton. Precise passing and clever finishing gave slim chance to Swans stopper Scott Reed, as the forward calmly rolled under the onrushing keeper for the first of the morning.



Ten minutes later, and continuing to press high, wideman Ferry doubled the advantage by latching onto a pacey delivery from Roland Idowu.



The run, timely and direct, was unchecked by the Swansea backline and allowed for an easy header at the back post, as Ferry netted his third of the season.



Robise was again involved in the away side’s final goal, this time holding the ball up well and winning a free-kick deep into Swans territory.



Ferry, on dead ball duty, floated a cross into the area, where Olufunwa had shrugged off the challenge of his marker, and darted across the face of goal to glance a 47th minute header in at the near post.



Saints were three to the good, and looking comfortable, but hadn’t killed the game off completely. Perhaps stepping off the gas a bit, the youngsters allowed their Welsh counterparts a lifeline in the 55th minute.



Evans, presented with a rare sight of goal after some sloppy Saints defending, took his opportunity to reduce arrears, sending the ball past Jack Bycroft and presenting the hosts with a glimmer of hope.



Saints then, determined to protect their lead and impending points, saw the remainder of the game out without too much threat, and made it three consecutive wins after overcoming a difficult start to their campaign.
