**Edinburgh triumphed 21-18 at three-time Heineken Champions Cup winners Saracens in their EPCR Challenge Cup opener on Saturday.** Mike Blair’s men have been in fine form in the United Rugby Championship, sitting second to Leinster after seven matches. They carried that level of performance into their Pool C curtain-raiser at the StoneX Stadium against the English Premiership’s second-placed side. Two early penalties from Emiliano Boffelli mitigated Alex Goode’s try for the hosts before a Ramiro Moyano touchdown – converted by fellow Argentine Boffelli – gave Edinburgh a 13-3 lead.
