Rochdale had to settle for a draw against Boston despite dominating.
On-loan striker James Keene gave Boston the lead with his first goal for the club on eight minutes, slotting home after good work from Mark Greaves.
Rochdale drew level in the 29th minute when Rickie Lambert's corner caused problems in the Boston defence and Gareth Griffiths headed in.
In the second half Boston keeper Conrad Logan had to make saves to keep out Chris Dagnall and Ernie Cooksey.
