Pompey failed to put any daylight between themselves and Fleetwood after the sides shared the points at Fratton Park.
And Sean Raggett admitted it was frustrating not to claim a maximum haul in the battle for League One promotion.
The defender’s looping header cancelled out Barrie McKay’s opener, with Harry Souttar then scoring at both ends of the pitch in a 2-2 draw.
Now Raggett is hoping that the Blues can put a string of victories together to ensure a successful end to the season.
He said: “It was two decent sides who are going for promotion, but we’re still disappointed not to come away with the three points.
“When we go ahead, I generally feel like we can see the game out, although they managed to get an equaliser.
“If that happens then you’ve got to press and try to get another. It didn’t come this time and we’ll keep working to get better.
“We feel like we’re a good team for set-pieces and so it was frustrating to concede from one, but that will happen at times.
“It was a lot better than Saturday and we’ve had some good runs this season, so now we need to go on another one.”
Raggett doubled his goal tally for the campaign by converting Ross McCrorie’s cross before the interval.
He said: “I saw him put the ball back in and I just had to gamble – I was either going to get my head on it or be absolutely munched by their defenders.
“It felt good as soon as I made contact and I knew the keeper was off his line a little bit, so luckily it looped over him.”
