With a weakened squad it was a good start from Calverton who pressed their opponents all over the pitch and worked hard to keep Rose at bay for the opening 20 minutes.
Calverton enjoyed some good possession down the left, but weren't able to carve out a clear cut chance before Rose took the lead midway through the first half, finding space in the Calverton defence, playing the ball in from their left and with time and space to control the ball and turn, the Rose attacker fired a shot across Armstrong for a 1-0 lead.
Steve Beresford snatched a couple of half-chances to try and bring Calverton level before the break, but nothing to test the visiting keeper.
Sumon Rogerson had the best chance of the half for Calverton; Scott Daley's free kick from the left finding him unmarked in the penalty area, but the header was off-target.
The second half was much harder work for Calverton, playing in to the wind, and Rose enjoyed the majority of the possession. Calverton forced a few more free-kicks as the game wore on, but the Rose defence were solid and the inevitable second goal came 15 minutes from times to seal all 3 points for the visitors.
