Bath Rugby earned two points against Northampton Saints but a last-minute try for the visitors earned them a narrow victory at the Rec.
The Blue, Black and White led 17-7 at half-time courtesy of tries from Max Clark and Will Muir, as well as Danny Cipriani's boots.
Ben Spencer's second-half 14-point haul extended Bath's advantage and secured a try bonus point but Saints hit back and scored four tries in the final 15 minutes to turn the result on its head.
