Aviva Premiership round-up: Wasps thrash Harlequins, Worcester edge Newcastle

Wasps 47-18 Harlequins
Wasps served up a seven-try show as they brushed aside Harlequins 47-18 at the Ricoh Arena to make it five wins from five in the Aviva Premiership.
Led by a storming display from powerhouse number eight Nathan Hughes, the hosts had the bonus point banked before half-time.
Despite easing off in the third quarter, Wasps added a touch of gloss to the final scoreline with three late scores as they went back to the top of the table.
Worcester - Newcastle
Worcester secured their first win of the Aviva Premiership season as Newcastle were beaten 11-9 in an error-strewn game.
The match was played in perfect conditions, and on the plastic pitch at Sixways, yet still both sides conspired to produce a very poor advert for the competition.
Worcester's Wynand Olivier scored the only try of the game with Ryan Lamb and Tom Heathcote kicking penalties.
Newcastle at least claimed a bonus point thanks to two Mike Delany penalties, and another late on from Joel Hodgson, to finish a game that neither side deserved to win.
