With a significant margin of 39 to Newcastle’s 8, Harlequins made it 13 wins from 13 this season so far, extending their Premiership lead to nine points.
Newcastle looked hopeful in the opening stages but Quins dominated on possession and territory, throughout. The result, combined with Worcester's win over Bath on Friday, leaves Newcastle nine points adrift at the foot of the table.
"That was incredibly physical. We have some walking wounded in the dressing room, but they'll get over it” said Harlequins Director of Rugby Conor O'Shea after the match.
"The win is fantastic because Nick Easter spoke to the players before the game and said they'd really have to turn up or get beaten. They turned up. He played fantastically well in the first half before tweaking an ankle which is why he went off.
"Jordan Turner-Hall is pretty beaten up after making the mistake of running into Taiasina Tu'ifua, and there's only ever one winner in that situation."
Meanwhile, Newcastle head coach Alan Tait admitted there’s work to be done:
"We have some guys a bit busted up in there, but they are the top side in the division and we pushed them at times only to let ourselves down with poor finishing.
“We say it every week in the dressing room but then we go out and give sloppy offloads, throwing the ball away. One minute we are attacking, the next they are away off our ball and scoring tries.
"I'll make some of them watch the video of the game during the week because we cannot keep doing this."
