Jordan Burrow and Danny Johnson struck within four first-half minutes as Gateshead brushed aside Chelmsford City 2-0 to reach the second round of the FA Cup.The Heed should have been ahead early on, but defender Neill Byrne blazed his close-range effort over.But the hosts took a deserved lead on 30 minutes when Wes York's teasing cross from the left was perfect for Burrow, who glanced a header beyond Michael Spillane.The home side doubled their lead just four minutes later - Russell Penn teeing up Johnson before the striker dispatched a curling effort from the edge of the area into the bottom corner.Chelmsford improved after the break with substitute Tom Hitchcock seeing a header tipped around the post by James Montgomery before the Gateshead stopper did well to parry a Shaun Batt free-kick.There was no comeback for the Clarets, however, as the Tyneside hosts clung on to secure victory.
