Leaders Bath inflicted a record Gallagher Premiership defeat on 14-man Saracens as they won 68-10 at the Recreation Ground.
Bath had the bonus point secured before half-time, such was their dominance in the first 40 minutes that Saracens winger Toby Knight was sent off and full-back Liam Williams booked, while flanker Theo McFarland and winger Tobias Elliott suffered game-ending injuries.
Knight was sent off in the 14th minute after a direct header in a challenge on Bath center Ollie Lawrence and Saracens had a mountain to climb after that.
They ended the afternoon reeling from the worst reverse in Premiership history, overcoming a 65-10 defeat by Exeter in October 2023.

The story of the match
The game started brightly and Bath were awarded a penalty by referee Karl Dickson after just five minutes.
Russell's cross aimed at Cokanasiga was fouled by Williams behind the line, which saw the Wales international booked and the visitors trailing by seven points.
Saracens also saw McFarland and Elliott go off injured during a frantic opening, then number eight Ben Earl canceled out a try after a forward pass from Gareth Simpson.
And just when Saracens might have thought things couldn't get any worse, Knight was dismissed before Bath winger Ted Hill broke through their defense and Du Toit crossed for a try which Russell converted.

Burke's penalty opened the scoring for Saracens after 20 minutes, but Bath went back on the attack and claimed a third touchdown when Redpath crashed over after receiving a pass from skipper Ben Spencer. Russell converted to make it 21-3.
Bath looked to make their numerical advantage count and the bonus point try arrived three minutes before half-time.
Spencer made a sharp break from the base of the scrum and his timely delivery allowed Muir to run unopposed 25 meters to the line.
Russell's conversion made it 28-3 at the interval, with Saracens on an extended damage-limitation exercise after such a disastrous first quarter.
Bath's Joe Cokanasiga scores his side's fifth try against Saracens
Bath were in no mood to show mercy and try number five arrived shortly after the break when Lawrence made a half-break and delivered a delicious one-handed pass to Cokanasiga, who scored easily.
Saracens tight end Nick Isiekwe did not return for the second half through injury and then Williams went off for a head injury assessment before Muir collected his second try, converted by Russell, as Bath made it 40 points.
They kept Saracens hungry in the line and substitute Underhill was the next beneficiary, rounding off a comprehensive move that had Muir and Miles Reid at its heart.
Russell's fifth successful conversion took Bath within touching distance of a half-century, although Saracens at least got a consolation when Pifeletti crossed and Burke converted, before Lawrence's try took Bath past 50.
Bath predictably had the last word when Cokanasiga pounced for his second try, before Muir completed his hat-trick and Russell converted both to complete the relentless demolition job.
