Aaron Morris scored two tries as Harlequins beat Bristol 24-12 in their Premiership Rugby Cup opener at Twickenham Stoop.

After Brett Herron opened the scoring with an early penalty, the two efforts from full-back Morris helped the hosts go 17-0 up before Tom Pincus replied just before the break with a try that went unconverted.

Charlie Mulchrone subsequently added Harlequins' third try in the 77th minute, with Mat Protheroe registering the visitors' second moments later.

Harlequins' next match in Pool 2 is away against London Irish next Saturday, September 28, a day after Bristol host Gloucester.
