The game was even throughout with Lonergan saving Preston in the first half whilst Agyemang failed on several occassions including one where he past the keeper but could not convert.
The decisive moment came in the second half when a slow Mawene was beaten to the ball and he could only bring down the Blackpool forward in the box. The penalty was duly converted.
Mellor came on and made an impact up front and referee Clattenburg who gave two penalties in the Merseyside derby earlier this season failed to do the same here. Mellor beat his man only to be hacked down in the area. Clattenburg believed the foul to be outside the area and failed to consult his assitant. The free kick was wasted.
Preston piled forward and hit the bar in injury time but could not force the equaliser.
