Rochdale overcame the stubborn and at times cynical resistance of their visitors to mark up a fourth successive league win, courtesy of spectacular strikes from New Zealander Leo Bertos and midfielder Ernie Cooksey.
The home side were on top virtually from the off but it took them 62 minutes to break the deadlock.
Leading scorer Grant Holt turned provider with excellent hold-up play before feeding the ball into the path of Bertos who found the bottom corner from 15 yards.
Midfielder Cooksey added a spectacular second to wrap up the points with just seven minutes remaining.
Having chested the ball down deep inside his own half he raced fully 40 yards, with the Boston defence retreating in front of him, before firing into the bottom corner from 25 yards.
After a poor start to the season Rochdale are now moving up the table rapidly and, despite having the smallest squad in the football league, are now making a genuine bid to join the fight for the play-off places.
