Pompey climbed into the top half of the Merit League One table with a comfortable 3-1 victory at Luton.
They broke the deadlock when Alfie Stanley (pictured) collected a pass over the top, spun sharply and drilled the ball into the bottom corner from outside of the box.
And the striker soon added his second of the contest by converting a whipped delivery from Eoin Teggart.
Stan Bridgman netted a third goal for the visitors before the break, following up to score after Oscar Johnston’s initial effort had been saved.
Luton did manage to reduce their deficit in the second half, but the Blues saw out the closing stages to secure all three points.
Academy manager Mark Kelly said: “It was a really good all-round display and we had plenty of control throughout the game.
“There was some clever play and a fine finish from Alfie to give us the lead and we were clinical to add two more before half-time.
"It was a really good all-round display and we had plenty of control throughout the game."
“We came out strong again after the break and created plenty of chances, with Ethan Robb missing a header from a few yards out.
“But Luton made some substitutions, threw everything they had at us and managed to pull a goal back.
“So we had to be a bit more narrow after that and show some discipline to see the match out and make sure we got the win.
“I was really pleased with our overall performance. We showcased some neat finishing and clever play to get into the final third.”
