Ten-man Boston recovered from two down to hold Altrincham to a 2-2 draw in the National League.
Goalkeeper Cameron Gregory saw red in the 50th minute after bringing down Justin Amaluzor when he was clean through on goal.
Altrincham immediately piled on the pressure and Elliot Osborne hit the bar before Alex Newby and Regan Linney struck within a minute of each other (66 and 67).
However, Boston mounted an impressive comeback, with Keaton Ward firing in a loose ball in the 78th minute and Cameron Green finding the net from long range six minutes later to secure a point.
