Bailey Peacock-Farrell was on hand to make the first save of the afternoon, with the Seasiders shot stopper pushing away an effort from Matt Phillips following a quick counter attack from the home side.
There was a couple of let offa for Ian Evatt’s side towards the end of the first half.
The first was a big miss by Phillips, with the former Blackpool figure firing over from close-range after Boro were gifted time and space in the box.
That was followed by a piece of goalkeeping brilliance by Peacock-Farrell. After stopping an initial Jasper Pattenden header, the Northern Ireland international reacted quickly to deny the midfielder on the rebound as well.
The first real chance of the second half came just before the hour mark, with Leighton Clarkson hitting the post with a free kick from the edge of the box.
Stevenage broke the deadlock on the 66th minute, with Harvey White slotting a shot through several bodies after a slow attempt to slow the midfielder down on the edge of the area.
Phillips had a chance to swiftly double the lead, but fired a shot just wide of the back post after outmuscling Jordan Brown to create some space for himself.
The result in Hertfordshire keeps the pressure on Evatt’s side, who are just above the third tier’s League One relegation zone, alongside wins for both Wigan Athletic and Exeter City out of the teams around them in the table.
Here’s how the Seasiders performed:
