Portsmouth manager Guy Whittingham said he had been expecting his side's first success since October after they ended a 23-game wait with a 2-1 win at Crewe.
First-half goals from Patrick Agyemang and David Connolly had put the visitors in the driving seat before Mathias Pogba pulled one back for Crewe.
But despite dominating second-half possession Crewe could not find the equaliser and the south-coast club held on to complete the double over their hosts.
Whittingham said: "There is a huge sense of relief. We didn't like to say it, but we felt it was building and the team was starting to gel so to come away and get that first win in many a while is just great.
"You can't be happier for anyone than the fans who have been superb again - they haven't stopped singing and this is as much for them as for the players.
"We were getting worried and tense towards the end which is natural for a team that hasn't won for so long. It was nerve-racking, but we got our bodies on the line and held on.
"It was like we had got promoted when the fans came on the field at the end, but we have to keep things in perspective. It's one win and there is another game next week now.
"Hopefully this will give us some confidence to move on and get some more points on the board."
Alex boss Steve Davis admitted his side had been "inept" in the first period, and he said: "We didn't defend well enough for their goals and we didn't create enough. The crowd showed their lack of appreciation and quite rightly so as there was a lack of effort drive and ideas.
"We went long and tried to miss out a lot of the pitch because of the condition of the pitch. First half we were inept, but second half we were much the better side and might have nicked it. We had a lot of crosses and got a lot into the box, but we never had anything really clear-cut."
