St Helens missed the chance to return to the top of the First Utility Super League after their thrilling second-half fightback in the final match of the Magic Weekend in Manchester was cut short by a revitalised Warrington.
Three-quarters Rhys Evans and Joel Monaghan each scored two of the Wolves' eight tries in a 41-24 success which was sweet revenge for a 38-8 mauling at home by Saints in their opening match of the season.
Saints were heading for a humiliating derby defeat when they trailed 36-6 early in the second half but they rallied superbly to provide fitting entertainment for a second-day crowd of 28,214, which helped establish a Magic Weekend attendance record of 64,552, eclipsing the previous best aggregate of 63,716 at the Etihad Stadium in 2012.
It was Warrington's sixth win in eight Magic Weekend fixtures and will give breathe new life into their flagging campaign.
Castleford got their Super League title charge back on track with a ruthless demolition of a poor Wakefield in a mismatched start to the second day of the Magic Weekend in Manchester.
Stand-off Marc Sneyd was the star of the one-sided show with two of his side's nine tries and seven goals in a 50-12 triumph as the Tigers bounced back from successive defeats to reclaim third place in the table.
Livewire hooker Daryl Clark and blockbusting winger Justin Carney also scored two tries apiece for Castleford, who gained a 49-24 win over their near-neighbours 12 months ago and were once more simply in a different class as they condemned the out-of-touch Wildcats to a sixth defeat in eight Magic Weekend fixtures.
Huddersfield showed no mercy to their stricken neighbours Bradford as they cruised to a fifth straight win to consolidate their place in the top six.
The Giants had nine different tryscorers as they revelled in ideal conditions at the Etihad Stadium to pile on more agony for relegation-threatened Bradford with a 54-16 triumph.
Danny Brough led the charge with a try and nine goals for a personal haul of 22 points, while there were also tries for Joe Wardle, Shaun Lunt, Luke Robinson, Jodie Broughton, Scott Grix, Ukuma Ta'ai, Anthony Mullally and Larne Patrick.
