Bath conceded their most points in a Premiership game in defeat by Saracens.
Sarries had picked up the try-scoring bonus point inside 30 minutes thanks to a double from Max Malins and a try apiece for Maro Itoje and Jamie George.
Ben Earl went over in the corner before George notched his second score to give Sarries a 45-0 half-time lead.
Tom De Glanville got Bath on the scoreboard but Eroni Mawi, Rotimi Segun and Dom Morris all touched down and Malins completed his hat-trick.
Bath showed some character to score two late tries through Tom Ellis and Will Muir but it did little to take the gloss off Saracens' win or provide much solace to the bottom side.
Stuart Hooper's men have now lost all four of their Premiership games this season.
The visitors raced into a 10-0 lead inside the first six minutes and never looked back as they recorded more than 70 points for only the second time in the Premiership.
England captain Owen Farrell kicked an early penalty before Itoje made the most of some lax Bath defence to run in a try on his first appearance of the season.
Sarries then weathered home pressure before adding to their lead through Malins' stylish try after forward Billy Vunipola had set up excellent field position when he kicked a 50-22.
George then dived over for a his second try in successive weeks after Sarries got a driving maul rolling towards the Bath line.
Just moments later the away side had their fourth try before the 30-minute mark as Malins sprinted in an interception from Danny Cipirani's loose pass.
Bath had more good field position before the half was out but were unable to come up with any points again thanks to a combination of poor handling and excellent defence from Sarries.
Their miserable first 40 minutes was capped off when Earl touched down in the corner and George went over from close range again as the five-time Premiership champions ended the half with a huge lead.
De Glanville raced in from Cipriani's pass as Bath reduced the arrears inside the opening minutes of the second half.
However, it was not long before Sarries got on the scoresheet for the first time in the second half when Mawi rumbled over and Malins then completed his hat-trick after the visitors moved the ball quickly from right to left after a line-out.
Segun and Morris both went over in the corner as Bath's weak resistance was broken with far too much ease and Saracens extended their lead to 71-7.
Ellis' and Muir's tries stopped Saracens surpassing their record 78-7 victory against London Welsh in 2014, but this was a hugely chastening afternoon for Hooper's men.
There was also some cause for concern for England coach Eddie Jones, who was watching on from the stands, as Itoje and Bath's Anthony Watson were both forced off with injuries.
Jones names his squad for the 2021 Autumn Nations Series on Monday.
Bath director of rugby Stuart Hooper:
"It's as bad as it gets, what we've seen there today, and our responsibility is to stand up and be counted.
"It is too easy to turn your back and have a conversation in the corridor. Let's front it up.
"It's gone really badly today. That pain we feel right now, we need to feel it. I don't believe you can just forget about it.
"My motivation for this job has always been the same, and it's about this great club, supporters and the players."
Saracens director of rugby Mark McCall:
(On forthcoming England squad) "If Eddie wanted to see if they had the motivation and desire to still play for England, then they showed that today. I thought Owen (Farrell) was brilliant today as well.
"I thought Billy was unreal. Mako as well. The two of them were to the fore in the defensive sets.
"There is a new squad tomorrow, and I expect to have a lot more players back in it. They deserve to be there after the way they played today.
"It was how physical, confrontational we were, dominating the gain-line. We've got players who can make things happen."
