The youth team let a two-goal lead slip against Tranmere Rovers in a disappointing 2-2 draw yesterday.
Kit Gregory opened the scoring just before half-time when he went on a mazy run past the Rovers defence and shot from outside the area past Patrick Wharton.
Gregory played a part in the second goal when he went on a similar run early in the second-half and laid the ball off to Elliot Pond, who coolly finished to double the side’s lead.
Ciaran Donnelly’s side were cruising towards a win but a lapse in concentration during a short spell in the second-half cost his side dearly.
The Seasiders were let off when they gave away a penalty for a foul in the area, as James Hunter blazed over from the spot.
Soon afterwards, Rovers pulled a goal back through Samuel Ilesanmi whose shot appeared to be going wide but the wind tucked the ball into the bottom corner.
The visitors got a second goal in quick succession just a minute later through Jamie Heron after the ball was pulled back for him by a team-mate.
Blackpool had earlier appeared to be 3-0 up when Rowan Roache threaded the ball into the path of Gregory, but the linesman adjudged him to be in an offside position.
Ciaran Donnelly said: “To score two good goals and get a two nil lead you think we would go on to see the game out. I’m just surprised because our lads generally were pretty tight at the back so to have a mad five minutes where we conceded a penalty and then to concede two goals in two minutes after that is out of character, really.”
