Gosport's unbeaten run was extended to seven games thanks to a spirited fight back against Mangotsfield United.
Boro' had a good start with Justin Bennett having an early chance but it was the visitors who took the lead after only nine minutes. A neat move and superb pass from Neil Arndale presented Marcus Duharty with the chance to shoot past Ashmore from ten yards.
Gosport's reaction was immediate and James Ford went close before the equaliser came on 23 minutes when Steve Claridge turned neatly on the edge of the area and hit a left foot drive past Greaves.
Brett Poate and Adam Wilde both went close for the home side and just before the break, had Nathan Kirby chose to pass to Bennett who had the goal at his mercy, Boro' would have gone in a goal ahead.
But it was United who opened the second half better and Gary Colborne was allowed to head unmarked at Ashmore's goal from only six yards but fortunately for the home side his effort went wide.
Claridge then mis-hit his effort after Bennett had set him up only for the strike duo to then set up Kirby. The midfielder cracked a shot that was handled in the area and the referee immediately awarded the penalty that Adam Wilde blasted to give Boro' the lead.
Gosport went in search of number three and Greave pulled off a fine save to deny Bennett but United were not out of the game and twice came close to an equaliser before the final whistle after Page crashed a header off the crossbar and the same man was denied by a great tackle by Poate as he was lining up to strike.
