Pompey certainly deserved something for their efforts, but it appeared as though another defeat was on the cards.
Ryan Hardie had cancelled out Lee Brown’s free-kick and the Plymouth striker then struck again late on at Fratton Park.
But the home side kept plugging away and were rewarded in the fifth minute of stoppage-time, when Ellis Harrison nodded down a Ronan Curtis cross for Sean Raggett to slide home.
It was met by delirium in the stands, even if the man who scored was slightly annoyed that they only claimed a point.
Raggett said: “It was a good feeling, but there’s also frustration because in the first half we had total control of the game.
“There was disappointment about letting in two poor goals after the break when we’d been on this run of bad form.
"It was very loud when it went in, but you expect nothing less at Fratton Park. The atmosphere was crazy."
“But we just needed to get out of this rut and so to pop up in the final minute and get the equaliser was great.
“It was very loud when it went in, but you expect nothing less at Fratton Park. The atmosphere was crazy.
“We were straight back to the centre circle to see if we could get another, but unfortunately there wasn’t enough time.
“The boys kept fighting and the execution of certain things wasn’t great, but the fans reacted to the attitude and energy.”
A draw ended the Blues’ run of three successive League One defeats and Raggett believes they are close to clicking again.
The centre-back said: “We had a really positive start and then this bad run of results, but I don’t think we’ve been too far away.
“It’s not like we’ve been battered by any team – there are just little bits here and there. It’s still early and if we get those right, we can get some good form together.”
