Sean Raggett scored a last-gasp winner as Dover extended their unbeaten run to four games after beating Altrincham 2-1 in the Vanarama National League clash at Crabble on Saturday.
The young defender scrambled home after substitute Jack Parkinson's cross hit the bar to secure Whites a deserved three points and their second win of the season.
Duane Ofari-Acheampong gave boss Chris Kinnear's side the lead in the 22nd minute when he turned home Stefan Payne's cross via the underside of the bar.
The visitors equalised through George Bowerman's 18-yarder four minutes before half-time.
The points looked destined to be shared before Raggett settled the issue and earn his side a first win since the 3-2 defeat of Kidderminster in the second game of the season.
Whites followed up that win with consecutive draws against Chester and Aldershot Town.
And just like those draws, it was again a game Kinnear's side created plenty of opportunities by failed to capitalise on them.
Ricky Miller had a header saved by goalkeeper Stuart Coburn in just the second minute before Ofari-Acheampong headed over when well placed six minutes later.
Nicky Deverdics volleyed over before Ofari-Acheampong scored to reward Dover's pressure.
But it was the visitors who went closest next when Deverdics headed Scott Leather's header off the line.
After that escape, Dover continued to press with Raggett heading over and Deverdics shooting wide from Miller's pass.
Bowerman put Altrincham back on level terms against the run of play when he cut inside from the right and fired past Walker.
Ofari-Acheampong had the first chance of the second half, firing well wide in the 60th minute before Payne saw his shot from Sam Magri's shot saved by Coburn.
Coburn then saved Miller's shot before he claimed Raggett's header with ease from Deverdics' corner.
Liam Bellamy's surging run ended with him shooting just wide from 30 yards before Raggett finally made the pressure count.
Coburn saved Miller's initial effort before Parkinson hit the bar with the rebound.
Raggett got to the loose ball first and steered it home much to the delight of most of the 711-strong crowd.
Coburn was injured making the first save and limped off with Nicholas Clee, a winger, who had come on seven minutes into the half, taking over.
And he produced a couple of cracking saves to deny Miller and Parkinson.
The win sees Dover move up three places to 10th.
