Mitchell’s free-kick forced Thornley’s keeper into the first real save, and Seaham kept up the tempo to break the deadlock as Punshon nutmegged his marker on the left and played a cornfield ball to the marauding right-back, whose cross was clinically dispatched over the keeper’s head by Jason Mitchell
