Saracens, who host Edinburgh Rugby on opening weekend, responded through Elliot Daly and Max Malins before the half.

Malins added another early in the second half before Nick Tompkins dotted down for the bonus point try – the teams tied at 27-27 heading into the final 20 minutes. Daly then kicked Saracens to victory with a 66th minute penalty.
