Sutton United grabbed a late goal to take a share of the points from a tight game at Victoria Park.
Rhys Oates put Pools ahead in the first half but Tommy Wright pulled a last-minute goal back for his side in a game that finished 1-1.
Jonathan Franks had the first chance of the game after just four minutes as he turned into space to fire one in from distance, which went wide of the far post.
Pools were back on the attack just a minute later as Rhys Oates crossed in from the left for Devante Rodney waiting in the middle; the ball was intercepted though by Aswad Thomas whose heavy touch sent the ball towards goal and over the bar.
The visitors had their first real chance just before the tenth minute as Nicky Bailey hit a well-taken freekick which beat the wall and had Scott Loach at full-stretch but went just wide of the post.
Loach was called into action as Sutton pressed in numbers and when the final shot came in from Jamie Collins, the Pools keeper once again pulled off a great block to deny a goal.
Josh Taylor played the ball out wide to Kieran Cadogan as Sutton continued to press; Cadogan skipped past Michael Ledger to push into the box and cross for Ross Lafayette on the far side. His shot at goal though was deflected over by Carl Magnay.
The visitors gave Pools little time on the ball, closing down quickly and leaving no room for error.
Harrison’s side were patient though and soaked up a period of pressure from the visitors before easing their way back into the game.
And, after a few flashes of promise going forward, Pools took the lead on 39 minutes the move started with Deverdics who picked out Rodney. The big striker took the ball into the box before trying his luck with a low effort on goal – his strike was blocked but only as far as Rhys Oates who simply knocked the ball home to make it 1-0.
Pools took their 1-0 lead into the second half, which kicked off with a higher tempo and plenty of hard work from both sides.
Carl Magnay put in a couple of great blocks for Pools in the box early in the half at one end, while at the other Jonathan Franks did well to open things up for his side and fire on goal. The shot was parried by Jamie Butler but Devante Rodney was waiting to pounce from close range, but he just couldn’t get the angle right and the ball hit the side netting.
Goalscorer Rhys Oates put in a great defensive header to clear a Sutton corner as the visitors enjoyed a spell of possession on the hour mark, a spell which also saw Pools twice clear the ball off the line as it cannoned around the box.
Pools had plenty of defending to do in this second half but did so strongly and as a team.
Bailey tried a spectacular effort with a freekick from 30 yards but Loach held the long-range effort and Pools were soon on the attack, with sub Blair Adams causing problems with a succession of crosses from the left.
The latter of his crosses picked out fellow sub Connor Simpson rising highest in the box but the young striker’s header went just wide of the far post.
The final ten minutes were end-to-end with frustrations showing on and off the pitch as both teams battled hard for the next goal.
Blair Adams blasted one just wide from distance for Pools at one end, while Loach tipped over the bar at the other.
With five minutes off added time, plus stoppage for an injury to Craig Eastmond, Pools were given a taste of their own medicine as Sutton grabbed a late goal to take a share of the points.
Tommy Wright smashed home a volleyed effort deep into the added time to make it 1-1 and secure his side a point from what was a closely-fought game.
