Hull KR moved off the bottom of the league as they shocked Wigan to win 24-8.
Junior Vaivai (2), Adam Quinlan and Chris Atkin all scored to provide Tim Sheens with a much-needed win against a Wigan side uncharacteristically poor in defence.
The Warriors had gone 8-0 ahead through a Joel Tomkins try and two Sam Tomkins goals.
But the hosts were 10-8 ahead at the break as Vaivai and Quinlan crossed, and they scored 14 unanswered points after the break to secure the victory.
