Wigan Warriors moved top of the Super League table on Friday with a 22-18 victory over Wakefield Wildcats, climbing above Hull FC, who were beaten by rock-bottom Leeds Rhinos.
Wigan came into the match level on points with Hull but ran in four tries to clinch an important win at DW Stadium, with Lewis Tierney crossing twice in the second half.
The victory came despite a first-half red card for Sean O'Loughlin, who was sent off for catching Chris Annakin high towards the end of the first half.
Wakefield took an 18-10 lead in the second half, but Tierney's double rescued the win for Wigan.
Kallum Watkins also registered two tries in Leeds' 20-15 victory at the KC Stadium.
The defending champions - trailing 13-4 at half-time - have already missed out on a place in the Super 8s, but are still having a say at the top end of the table after denting Hull's hopes of topping the regular-season standings.
Meanwhile, Huddersfield Giants threw away an 18-6 half-time lead to lose 20-19 at Hull KR - a defeat that consigns them to the Qualifiers while keeping Rovers' slim top-eight hopes alive with two games to go.
In the day's remaining fixture, St Helens were 12-10 victors over Widnes Vikings.
