Joel Moon haunted former employers Salford as Leeds came through their final Super League game before the World Club Challenge without too much of a fuss in a 42-14 victory.
Australian centre Moon was snapped up by Leeds following an impressive season with the Reds last year - he scored 11 tries in 19 games - and touched down twice, along with Paul McShane, as part of a classy display which also saw Stevie Ward, Kallum Watkins and Kevin Sinfield cross.
Moon was not always joined in excellence by his team-mates as Salford, who scored through Ashley Gibson's double and Niall Evalds' effort, occasionally made life difficult for Brian McDermott's reigning champions, but the Rhinos had enough about them to pull clear when they needed to.
Winger Joel Monaghan scored twice as unbeaten Warrington ended Catalan Dragons' 100 per cent start to the season with an ugly 24-16 win at the Halliwell Jones Stadium.
The Australian crossed twice and Richie Myler added another as the Wolves claimed a crucial early lead in a scrappy, ill-disciplined and controversial contest. Damien Blanch began a fightback with two tries but the game got beyond the Dragons, who twice saw Brent Webb sin-binned, when Rhys Evans touched down.
Zeb Taia reduced the arrears late on but the Wolves, who were unexpectedly without playmaker Lee Briers and played most of the game without early injury victim Adrian Morley, had done enough.
Australian stand-off Daniel Holdsworth put Hull into a winning position but failed to deliver the killer punch to leave the scores tied at 22-22 at Langtree Park.
The Black and Whites fought back from 22-12 down to draw level with the aid of Richard Whiting's 72nd-minute try and ought to have taken both points after dominating the final quarter. Jason Crookes, Shannon McDonnell. Tom Briscoe also went over for FC.
But Holdsworth, who had helped create all four of his side's tries, kicked three superb conversions, missed a kick to win it and was also wide with two long-range drop-goal attempts in a frantic finish.
That left St Helens relieved to salvage a point after once more looking distinctly out of sorts, with their efforts coming from Anthony Laffranchi, Francis Meli, Jordan Turner and Josh Jones.
