Saints took on Blackburn Rovers in the second leg of the Under-21s Premier League Cup final at St Mary's Stadium.
Saints took the lead against Blackburn with a goal from Ryan Seager, but Blackburn soon equalised after an own goal from Matt Targett.
Sam Gallagher scored during extra time, despite Harrison Reed being shown a red card shortly before the end of the 90 minutes.
