St Helens bounced back from their Challenge Cup defeat by Warrington as they thrashed a wayward Hull FC side.
The hosts led through Tommy Makinson crossing in the corner while Jonny Lomax touched down soon after.
Waqa Blake and James Bell went over to extend Saints’ lead as Joe Batchelor ran in a fifth try before half-time.
Mark Percival, Konrad Hurrell and Curtis Sironen added to Hull’s woes as Blake’s second broke the 50-point mark before Jack Welsby added a 10th try.
The visitors came into the match off the back of sacking head coach Tony Smith with half-back Fa’amanu Brown and full-back Tex Hoy following him in leaving the club.
Richie Myler also took over as director of rugby prior to the trip to the Totally Wicked Stadium during a chaotic period of change for the Super League strugglers, but interim coaches Simon Grix and Francis Cummins could not avoid Hull’s seventh defeat in eight league games.
Saints had suffered a chastening loss to the Wire in the Challenge Cup quarter-final on Sunday after a second half capitulation against Sam Burgess’ side, but there was to be no repeat in a resolute performance where they rarely looked threatened.
Their opener came in stylish fashion as a succession of passes, starting with Lomax’s offload eventually saw Hurrell offload to Makinson to touch down.
Hull FC were carved open again inside the opening quarter of an hour as Mata’utia sent Lomax through with ease while some quick hands under pressure saw Saints keep the ball alive to sent Blake through for their third.
Bell weaved his way through a dejected Hull defence while Saints picked up from where they left off after the break as Lomax sent Batchelor through with a move straight off the training ground.
Lomax teed up another Saints try as he sent Percival through to follow up his fine work with the boot and Hurrell later continued the rout on his 100th Super League appearance.
Sironen crashed over just before the hour mark and Blake ran in virtually unopposed for his second before Welsby cut in to wrap up a remarkable victory.
