Hughes spearheads Wasps triumph
Wasps 41 Harlequins 10
Nathan Hughes terrorised Harlequins as Wasps swept aside their Aviva Premiership rivals with a 41-10 bonus-point victory in a Champions Cup match in Coventry.
The England number eight spearheaded Wasps' five-try assault on Quins as Dai Young's men ended a miserable run of five straight defeats in style at the Ricoh Arena.
Joe Marler was perhaps fortunate to avoid a red card for a forearm smash to Will Rowlands' midriff, another unsavoury disciplinary incident for the England prop.
Hughes was the architect of Wasps' first try and produced two stunning hand-offs that sent first Chris Robshaw then Dave Ward hurtling backwards through the air.
Harlequins endured a tough night, their mood worsened in defeat on a day that had started with Marland Yarde being dropped from the match squad.
Quins issued a curt statement that the England wing had been "withdrawn from the squad following an internal disciplinary matter".
Yarde's disciplinary situation could dent his England chances, with boss Eddie Jones naming his squad for the autumn internationals on Thursday.
Marcus Smith endured another harsh lesson on the realities of top-flight rugby, with a charged-down kick leading directly to a try for Christian Wade.
Harlequins centre Francis Saili suffered a nasty-looking injury late on, carried off on a stretcher following lengthy treatment owing to a head-first collision with Joe Launchbury's hip.
Josh Bassett wriggled home for Wasps' bonus-point score thanks to Elliot Daly's wide ball, before Wade glossed the result with an intercept try.
