Dagenham and Redbridge kept a clean sheet and extended their run to only one defeat in eight games.
Jodi Jones became the youngest ever Dagenham & Redbridge player when he replaced Alex Jakubiak
late in the game.
The game began at an incredible pace and saw chances at both ends and a strong penalty appeal when Jamie Cureton
felt he was tripped by Joe Devera.
Cureton, fresh from his brace against York at the weekend was causing the Pompey defence all sorts of problems. After 15 minutes, he used his pace to get past Dan Butler and get a shot away but it was dealt with by Paul Jones in the Pompey net.
Pompey had a few chances of their own and Mark Cousins
had to be aware when a powerful header from Devera but the Daggers 'keeper held on to the ball with a safe pair of hands.
played well throughout the 90 minutes and was first to every loose ballm it was from one of these loose balls that he launched a Daggers attack which culminated in Jakubiak flashing a powerful shot across the goal but to no avail.
Ayo Obileye extended his loan with the club until the end of the season during the week and similar defensive displays such as the one shown against Portsmouth will certainly be welcome.
The defender had to be alert to prevent Matt Tubbs running through on goal late in the first half.
had a chance to give Daggers the lead in spectacular fashion when Ashley Hemming's pass found Boucaud in space 35 yards from the goal, Boucaud let off an incredible strike that just whistled past the outside of the post leaving Jones rooted to the spot in the Pompey goal.
continued his recovery from injury with a solid 90 minutes and earned the point for Daggers late in the game with a sublime tackle on Paul Robinson.
