With four points from their last two matches there was a positive feel to the opening exchanges but that only lasted until James Keene put Boston United one up after seven minutes.
Keene was the third Boston player to have a stab at scoring after a short centre from the right and he nearly broke the net with a shot almost on the goalline.
It took Rochdale 22 minutes to level it and that was when Gareth Griffiths headed home.He met a corner from the right after coming up from his defensive position.
After that both sides had lots of chances with Rochdale getting the best one close to the end when the usually reliable Rickie Lambert tried to lob the goalkeeper who was miles off the line.
He beat the keeper but with the crowd behind the goal calling for a winner the ball lifted just wide of the target.
Earlier Julian Joachim nearly shaded it for United with a shot beautifully saved by goalkeeper Matthew Gilks and not long afterwards Keene nearly added to his goal with a similar shot to the one that had broken the deadlock.
A very late effort by Rochdale almost produced a winner from Chris Dagnall but he was just off target having worked his way into a good shooting spot.
