At Walter Road Reserve, the Gulls had cause for concern when Glory scored two goals inside the first 23 minutes and held the lead until half-time.
But a motivational speech from coach Jamie Harnwell kicked Sorrento into gear, the players using their experience to overcome Glory’s youth side 3-2.
The Gulls’ physical pressure became too much for their younger opponents as the away team went on to score three goals in the first 20 minutes of the second half.
Sorrento’s defence, where youngster Razack Geloo impressed, held its nerve to ensure the Gulls landed the three points.
Harnwell lauded the team’s fight back.
‘We are a physical side and if we need to use that to win games, we will do it,’ Harnwell told nplwa.com.au.
At ECU Joondalup Football Stadium, the 10th-placed Jacks were outclassed 4-0 by the second-placed Azzurri.
Perth scored twice in each half to secure a solid away victory.
