The Polish international was duped by the wind as the Potters keeper found the back of the net with a goal kick 13 seconds into the match at the Britannia Stadium.
Jay Rodriguez's goal just before half time ensured that the Saints left with a point, but Boruc was regretful following the match.
"This is my job and I should protect those kind of situations and in the end I didn't do anything," Sky Sports News quotes the 33-year-old as saying.
"That cost us two points and it is hard for the lads because they put a lot of effort into today's game and probably deserved three points.
"What can I say? I can promise I will get those two points back."
The result leaves the South Coast club fifth in the Premier League.
