A late Charlie Lakin penalty rescued a point for basement boys Sutton in a 1-1 draw with Grimsby.
The visitors picked up another point on the road to safety, but it could have been more at Gander Green Lane.
Sutton had an early scare when goalkeeper Steve Arnold failed to gather a free-kick and Justin Obikwu’s goalbound header was cleared off the line by Craig Eastmond.
But Arnold was more convincing when he saved Harry Clifton’s low shot, and just before half-time denied Obikwu at close range.
However the Grimsby striker was not to be denied, and when Sutton failed to clear a corner his neat flick found the corner of the net a minute before the break.
Sutton’s first shot of note came from substitute Olly Sanderson but was comfortably wide.
Arnold was again called in to action to save from Kieran Green, and Harvey Rodgers hit the bar with a header from Gavan Holohan’s corner.
A handling offence spotted by an assistant following a corner saw referee Alex Chilowicz point to the penalty spot and Lakin hammered the penalty past Harvey Cartwright with two minutes left.
