Before the visitors had touch the ball prolific points machine Pat Richards
opened the scoring inside three minutes. Ryan Hoffman
added another one shortly later. George Carmon then ran in a third try after he intercepted Luke Gale
's pass just inside the Quins half in the 11th minute and Sam Tomkins
quickly added a fourth under the posts.
The Londoners were regularly making errors and Thomas Leuluai
punished another, jinking through to reach over before the Warriors scrum-half then spotted another gap to charge over from 15 metres soon after.
Hoffman made a break on halfway to set up Captain Sean O'Loughlin
for the hosts' seventh try of the half.
Harlequins saw more of the ball after the break but they posed little threat and it was no surprise when Tomkins touched down for his second try of the night.
Quins finally found a way on to the scoreboard when Luke Gale
recovered Karl Pryce's wayward pass to send ex Warrior Mark Calderwood over for a consolation.
But there was still time for Richards to have the last word as he charged over in the closing moments, and then he made it a perfect night with his ninth successful conversion out of nine.

to touch down.
