Matty Ashton scored a hat-trick as Warrington Wolves ended Hull Kingston Rovers' reign as Super League champions with a 35-12 victory in the play-off eliminator.

Warrington will now travel to play Leeds Rhinos at AMT Headingley on Friday, 25 September for a place in the Grand Final, with Wakefield Trinity taking on Wigan Warriors in the other semi-final the following evening.

The Wolves held a 12-6 lead at half-time before Peta Hiku was sent off for punching George Williams. Ashton's second try brought a response from Dean Hadley but Warrington ran away with it as Ashton grabbed his third, Albert Hopoate and Toby King also crossed, and Williams capped a fine display with a late drop-goal.

Defeat brought Willie Peters' successful reign as Rovers coach to an end as he leaves to join new NRL franchise PNG Chiefs next season. Hull KR produced an underwhelming display which reflected their inconsistent season.
