Steve Spooner’s Blues side had started the game well, but fell behind after half and hour, before conceding a second goal ahead of half-time.
Kyle McFarlane finished off an excellent move to bring Blues back into the game after 60 minutes, before the visitors struck twice more without reply to seal a comfortable win.
“The first 20-25 minutes I was very pleased with us,” said Academy coach Spooner.
“We played some decent football but without a cutting edge.
“Leeds’ first goal came after they broke from our corner and the second was caused by a misplaced pass by one of our players.
“We scored a very good goal after about an hour, when Kyle McFarlane was on the end of a move that involved seven or eight passes and came from the back.
“At that point we were right back in it, but we were caught sleeping at a corner for their third goal and then they scored again.
“This season we haven’t had many dips as a team, but Saturday was just one of those bad days at the office for us.”
