Blyth entertained last season’s runners-up Guisborough and got the hard game they expected as the visitors ran out 26-20 winners at Plessey Road.
The first 20 minutes were fairly even with both sides spurring scoring chances, but it was the visitors who took the lead when poor tackling by the Blyth backs let them through for two tries in quick succession for a 12-0 advantage.
Blyth went close to reducing the deficit after good work by Sutherland and Grey, but they were stopped just short of the line.
The home side eventually got on the board with two penalties for Sutherland and then took the lead with a fine try by Grey, the ball having been won at a lineout and spun along the backs for the full-back to join the line and score.
The score was converted by Sutherland to give Blyth a 13-12 interval lead.
The Blyth pack started the second half well and destroyed the visiting scrum on more than one occasion as they Guisborough under pressure.
But the visitors hit back with a forward drive of their own to regain the lead at 19-13.
The lead changed hands again when hooker Stephenson was driven over, with the conversion landing on the crossbar before bouncing over.
But Guisborough hit back and as a Blyth knock-on gifted them an attacking scrum from which they scored what proved to be the winning try.
At 26-20 down Blyth still had two chances for catch and drive lineouts, but with hooker Stephenson off the field with a broken nose they could not get the throw-in right.
The result sees Guisborough go above Blyth who are now second in the league.
Blyth have a free week this weekend before the trip to fourth placed Horden on November 23 with a 2pm kick-off
