Tommy Makinson scored a hat-trick as St Helens responded to their stunning defeat to London Broncos with a 38-2 drubbing of Huddersfield Giants and Wigan Warriors beat Super League strugglers Leeds Rhinos.
The bottom-of-the-table Broncos pulled off a stunning 23-22 upset of Saints last weekend, but the leaders put that behind them with a dominant display on Friday.
Makinson marked his 200th appearance for the club with a treble, while Jonny Lomax scored a try in each half and Theo Fages also crossed as the Giants were put to the sword.
Lachlan Coote was outstanding in a one-sided contest, the full-back scoring one try and creating five, while also booting five goals as Justin Holbrook's side moved six points clear of Warrington Wolves.
Wigan ended the Rhinos' mini revival, winning 23-14 at Headingley on a night it was confirmed Leeds captain Kallum Watkins will join Gold Coast Titans on July 1.
Oliver Gildart and Adam Cuthbertson scored the only tries of a first half which ended with the Warriors 11-8 to the good.
Trent Merrin's converted try put the Rhinos in front 10 minutes into the second half, but Oliver Partington's first Wigan try and a late Tony Clubb score gave the Warriors the victory to keep Leeds only two points ahead of the Broncos and Hull KR.
