Saints picked up three more valuable Vanarama National League North points.
Wilkin’s side beat lowly Ashton United 3-1 at St James Park on Saturday and the result narrows the gap to the play-offs.
A first half penalty from Shaun Jeffers and captain Gaz Dean’s 25 yarder put Saints in control. In the second half a strike from Matt Lowe sealed it before Jeffers missed the target with his second spot-kick and James Jones grabbed a consolation goal in stoppage-time.
Wilkin said: “We went about our work very well but I am disappointed to concede the goal at the end. We just haven’t been keeping enough clean sheets and have given away a sloppy goal in added-time, and also not to have scored more given the chances we created.
“I am delighted with the win but I am far from satisfied with where we are at the minute. If we are to be serious play-off contenders we need to sharpen up and improve in key areas.”
