Late tries from Pat Richards and Josh Charnley broke the hearts of Hull KR as Wigan Warriors secured the League Leaders Shield with a 36-42 victory.
The Robins had led 26-0 just before half time, but were were overtaken by a rampant second half display by Warriors at Craven Park.
While KR failed to rain on Wigan's Leaders Shield parade, neighbours FC did dampen the party at Bradford Bulls.
Winger Tom Briscoe scored a hat-trick of tries in a 6-70 victory as Hull turned party-poopers by putting a huge dampener on Bradford's celebrations at finding a buyer for the ailing Super League club.
The Bulls conceded 13 tries in their biggest loss of the year, which brought to an end a three-match winning run and cast serious doubt over their prospects of a first appearance in the play-offs for four years.
Hull winger Jamie Foster scored 26 points as Peter Gentle's men bounced back in impressive fashion from their humiliating loss to bottom club Widnes to cement sixth place in the table and breathe new life into their own play-off campaign.
