Albie Morgan opened scoring for the Seasiders in the 24th minute with a low-driven shot from the edge of the box finding the bottom corner.
The advantage was soon doubled by Rob Apter, with the winger finishing on the rebound after an initial attempt from Kyle Joseph was saved by Joel Pereira.
Just before that, the Royals keeper had also denied Ashley Fletcher – who saw his header from close-range pushed onto the post by the fingertips of the 28-year-old.
After the break, the striker eventually got his rewards for a big shift, with a goal from close-range coming from further good work by Joseph.
Here’s how the Seasiders’ performed against Reading:
