JJ Hanrahan's penalty seven minutes from time was the difference as Northampton beat Bath 13-11 on Saturday evening.
The Kerryman went three for three from his kicks - one of those being a conversion. The try which it followed was a gift for Northampton.
Coming under pressure from several Northampton players, Bath out-half George Ford threw a pass directly into the arms of Luther Burrell 15 metres from the line. With no one at home, the centre sauntered in for the opening try for the game.
