In the first half Boston showed some stubborn resistance making it difficult for Grimsby. The Blues managed to break the deadlock after 20 minutes with the ball being passed down the back line to centre Lewis Rothenburg who sprinted forward before laying the ball off to fly half Lewis Dyson who had looped round the back to score in the corner, giving them a 5-0 half time lead. In the second half Grimsby’s superior fitness and power came to the fore. The forwards began to dominate and following a drive by No.8 Ash Rendall-Tyrrell making good ground, prop Conor Simcock picked up the ball from the ruck and dived over to score. Rothenburg added the conversion. Minutes later fellow prop Richard Watson then drove over from another ruck to score. Flanker Huw Cowper scored an individual breakaway try from an interception sprinting from his own 22 to score under the posts leaving Rothenburg with an easy conversion. A good running line from full back Rob Bell led to a try when he cut inside and received a pass from Rothenburg to score. Grimsby continued to press and following a driving maul taking the ball over the Boston try line flanker Sam Fleming had the simple task of taking the ball, peeling off the maul and dropping to the ground to score. Winger Jordan Landymore finished the scoring when he received a wide ball from centre Brad Treacher and sprinted down the line to score in the corner to give Grimsby a 39-0 victory. The winning bonus point now means that Grimsby finish first and will play either Bourne or Ilkeston in the semi-final next Sunday at Sleaford.
