Steve Chettle’s side claimed 1 -0 victory over Morpeth, as James Reid bagged the only goal of the afternoon in the 32nd minute.
“It was hard fought,” Chettle told BasfordTV.
“It wasn’t pretty and we were hanging on at times. A great piece of quality from James Reid has won us the game.
“Like I said before the game, these are a dangerous proposition, Morpeth. They’re a good football team with good players and they proved that fact. We were hanging on but I’m delighted with the 1-0 win.
“We said as soon as the ball went down for the free kick, I fancy something Reid to go something special here and he proved that. It was fantastic.”
