Liam Farrell's late try secured an 18-14 victory for Wigan Warriors over Warrington Wolves, while St Helens continued to roll in Super League on Friday.
The Wolves led by six points at the break, with a penalty try and Chris Hill's score answered by Joe Greenwood for Wigan.
Zak Hardaker converted his own try to level the scores but a Stefan Ratchford penalty had Warrington just ahead going into the final stages.
But, just when it looked as though Warrington's brave defensive effort would yield its reward, Farrell took Harry Smith's offload to go over with four minutes left and Hardaker added the extras for second-placed Wigan to keep the Wolves fifth.
Leaders St Helens were made to work hard for an eighth straight Super League win, coming from behind to defeat Wakefield Trinity 20-16 in the first of the double header at Headingley.
Alex Walker and Craig Kopczak tries had Wakefield flying but their advantaged was reduced to 12-10 by the break, as Louie McCarthy-Scarsbrook and Lachlan Coote responded.
Regan Grace crossed and Coote had a second before Matty Ashurst scored a consolation late on for struggling Wakefield.
Catalans Dragons remain in the play-off race after outclassing Hull KR 34-4.
Joel Tomkins and Tom Davies scored twice tries apiece, while Ben Garcia and Israel Folau also touched down to send the Dragons above Leeds Rhinos into third spot.
