Superb Saracens secure top spot
The Premiership side produced a dominant display against their nearest Pool One rivals to enhance their credentials as potential winners of this year's Champions Cup.
A fourth bonus-point victory of the pool stages came thanks to tries from Billy Vunipola, Duncan Taylor, Maro Itoje and Schalk Brits.
Owen Farrell produced another superb display from No.10 and after a tricky start to the contest they never really looked like losing.
Farrell opened the scoring after just three minutes with his first penalty of the afternoon but it was the visitors who crossed for the game's opening try moments later.
A good break from centre Stuart McCloskey took Ulster into the Saracens half and after going through the phases Jared Payne's grubber kick was collected by Luke Marshall to score.
Farrell's second penalty on 20 minutes took them back to within a point, but both sides were finding chances hard to come by.
Saracens struck shortly before the break when No.8 Vunipola crashed over from close-range from a driving line-out and Farrell added the extras to give them a six-point advantage at the break.
Ulster came out firing after the break and Paddy Jackson's first penalty brought them back to within three points.
A third from Farrell restored their six-point advantage before a delightful show-and-go from the England international cut open the Ulster defence and he put replacement Taylor over in the corner.
It was the beginning of the end for Ulster as Saracens grabbed their third try on the hour, a driving line-out gave them good momentum and Itoje was the player to touch down.
Two minutes after the try Ulster were down to 14 men as wing Craig Gilroy saw yellow for not rolling away and it wasn't long before Saracens wrapped up the bonus point.
Another impressive driving line-out put Ulster under pressure and this time it was Brits' turn to come away with the try.
Ian Humphreys got a consolation try for Ulster 10 minutes from time when he scooped up a loose ball and ran-in from 40 metres.
