"It is very satisfying to be back at the top of the league looking down on everyone else," Pearson told the club's official website.
"I thought we played pretty well on the night and turned in a thoroughly professional performance.
"Yes, we'd like to have scored more goals and made the result more comfortable but, on days or nights where you can't do that, then you've just got to see the job through until the very end.
"I am delighted with another clean sheet and another victory, which has helped put us top."
