Chris Whelpdale's first-half header was enough to earn Stevenage a 1-0 victory at Newport County.The winger was in the right place at the right time to earn Borough their second successive League Two win. Newport's slim chances of making a late charge for the play-offs look to be over with the gap now 11 points with six games remaining.Nervous Newport goalkeeper Joe Day missed four punches clear in the opening half an hour and had Mickey Demetriou to thank for sparing his blushes.The defender rushed back to his line to deny Danny Newton a tap-in and keep the scores level after Day failed to connect with a looping ball into the area.But he was finally beaten by a cross after Stevenage skipper Ronnie Henry clipped the ball to the back-post for Whelpdale to nod into the net after 43 minutes.They almost doubled their lead seconds after the restart when Henry's long-range half volley was acrobatically denied by Day. Frank Nouble and Josh Sheehan both had penalty appeals waved away, but Newport never threatened to equalise.
