Pompey Academy began their Merit League One campaign with a 3-2 defeat at Swindon.
The visitors fell behind early on, but Eoin Teggart struck to ensure the sides went in level at the interval.
Swindon retook the lead early in the second half, although the Blues levelled again when Leon Maloney (pictured) followed up to score after Alfie Stanley’s initial effort was saved.
It looked like the spoils were going to be shared, only for the hosts to grab the winner with just a few minutes remaining.
Academy manager Mark Kelly said: “It was a free-flowing and competitive contest, although it was our first game for three weeks, so we were a bit rusty at times.
“We fell behind after some sloppy defending, but built ourselves back up and played some neat football, with Eoin levelling before half-time.
"It was a free-flowing and competitive contest, although it was our first game for three weeks, so we were a bit rusty at times."
“They scored again, although we were still creating quite a few chances and their keeper made some saves from point-blank range.
“Alfie swivelled and shot, with Leon following up well to equalise and we were producing some really positive stuff.
“Then, with just five minutes remaining, there was a bit of hesitation between Robb and Durin, with their lad nipping in to score.
“Swindon are a big, powerful team, but we looked good when we got the ball down and passed it around.
“There was some pleasing stuff from us and my only real criticism is that our final delivery was lacking in quality at times.”
