Lecce have clinched promotion to Serie A after defeating Albinoleffe 2-1 on aggregate in the promotion play-offs.
They had already won the first leg 1-0 in Bergamo and it proved decisive as they drew 1-1 in front of ecstatic home fans at the Stadio Via del Mare.
It took eight minutes to break through, as Elvis Abbruscato smashed in an angled drive from Simone Tiribocchi's through ball.
Polenghi had a couple of dangerous headers for the home side, but Albinoleffe got back into it 13 minutes from time with Francesco Ruopolo spinning round his marker to sweep home. But Lecce held on to secure promotion.
