Tries from Werner Kok and Sam Graham had given the Red Bulls a 10-point cushion at half-time with Jamie George's try sandwiched in between as they went in search of successive wins.

But a loss of discipline from the vistors in the second period changed the game as Graham and Alex Hearle were both yellow-carded.

In the 17-minute spell in which Saracens had at least a one-man advantage, they scored 22 unanswered points with tries from Sione Va'enuku, Toby Knight, Nick Tompkins and Noah Caluori.

Further scores from Elliot Daly and Rotimi Segun followed to make the game safe before two late efforts from Ollie Leatherbarrow and Hearle grabbed Newcastle a bonus point.

But despite that, a fourth loss in five matches sends them into the November break bottom of the Prem.

Replacements: George, Brantingham, Clarey, Martin, Earl, C Bracken, Malins, Caluori.

Replacements: Adejimi, West, Moreno, Baker, Leatherbarrow, J Elliott, Henry, Harris.

Sin-bin: Graham (45), Hearle (52)
