Stevenage assistant manager Kevin Watson praised his ‘terrific’ side following their last-gasp Fratton Park point.
Pompey appeared to be heading for a 1-0 victory through substitute Conor Chaplin’s 77th-minute strike last night.
Yet during five minutes of time added on, Charlie Lee launched a long throw from the right into the penalty area.
Brett Williams, who had just been introduced as a substitute, did the rest with a header which looped over Aaron McCarey and into the Blues’ net.
It was enough to secure a point for Sheringham’s side, who defeated high-fliers Wycombe 2-1 at the weekend.
Watson addressed the press rather than manager Sheringham after the match.
And he was quick to pay tribute to Boro, who have really improved their form.
He said: ‘We were terrific all night.
‘We kept our shape well, defended really well and restricted a very good team to very few chances and the boys defended excellently as a team.
‘I always felt we were going to get another chance in the game. We’re a big side with the bodies we have and it was a set-piece that got us the goal. We thoroughly enjoyed the draw.
‘Pompey’s goal may have been a mistake in defence, but it was good play from them.
‘Their lad danced around Dean Parrett and smashed it in. It was a good goal on their part, but one we’re not too pleased about.
‘On the whole we passed the ball very well and had a great opportunity to take the lead when Dipo Akinyemi missed a fantastic chance.
‘That’s three very good results now after wins against Plymouth and Wycombe.’
