History was made as Sky Sports broadcast the first-ever Men's and Women's Super League double-header as St Helens and Lees Rhinos went head-to-head at the Totally Wicked Stadium.
A dramatic finish in the opener between the club's Women's teams saw Leeds claim a last-gasp 20-18 win over Saints, before their Men's side swept their opponents aside in a 42-12.
Kicking off the evening's entertainment, reigning Betfred Women's Super League champions St Helens raced into a 14-0 lead after 22 minutes thanks to tries from Jodie Cunningham, Player of the Match Amy Hardcastle and Zoe Harris, who also kicked a goal.
But Leeds surged back late in the first half with two tries of their own through Caitlin Beevers and Jasmine Earnshaw-Cudjoe. Courtney Winfield-Hill kicked a goal for a 14-10 half time score to the home side.
Fran Goldthorp grabbed an early second-half try to make it 14-all before Tara Jones struck back on the hour to make it 18-14 to the home side.
A tense final quarter ensued and the Rhinos lost the ever-creative halfback Georgia Roche to injury, but they were able to find a piece of magic late on as captain Winfield-Hill manufactured space to produce a deft chip over the top of the defence. The ball fell to Goldthorp who kicked ahead and collected the ball before stepping over beneath the posts for 18-all.
Winfield-Hill notched the simple conversion for a memorable away win.
In the Men's Super League game which followed,St Helens went six points clear at the top of the table with a comprehensive win over the Rhinos.
Tries from Konrad Hurrell and Alex Walmsley, both converted by Tommy Makinson, who ended up with five goals on the night , put Saints 12-0 up after just 17 minutes.
Though a stunning try from Harry Newman, which Rhyse Martin goaled, provided some first-half hope, Saints added another try before the interval through Regan Grace to make it 16-6 at half time.
Kristian Woolf's side then clicked through the gears after the restart and kicked things off with a second Hurrell try.
Scores from Agnatius Pa'asi, Joe Batchelor, Dan Norman and Walmsley's second late on rounded off a comfortable evening for the home side.
