The Leeds winger’s 25 tries put him nine clear of the next best, Leigh’s Josh Charnley on 16.
In addition to leaving his mark on the game he left plenty on Warrington’s bruised defence, including Josh Thewlis who felt the full force of Sivo as the winger powered past him to score his second.
When Warrington took two points early in the piece, Ewan Irwin kicking the goal, it was presumably in the belief this could have been a tight affair.
But two tries in two minutes from Sivo and Brodie Croft, who has signed a three-year deal with Warrington starting next season, blew that plan out of the water and a third eight minutes later, Harry Newman gathering a high kick as Thewlis hesitated, really put the visitors in command.
Warrington were perhaps a touch unlucky that the Newman try stood with the Leeds centre looking a shade in front of the kicker when the ball went up but had that gone in their favour it would not have made much difference to the result.
Jake Connor kicked two of the conversions to give Leeds a 16-2 half-time lead and the direction of the game was set.
Miller, returning to the side after a three-match suspension was excellent, pulling the strings at full-back.
It was the Australian whose pass put in Chris Hankinson just three minutes after the restart and he then engineered a penalty when blocked by James Bentley two minutes later which Connor converted.
After Sivo secured his hat-trick shortly before the hour, Warrington staged a belated comeback in the final 20 minutes.
Matty Ashton finished off a nice move to give the home side their only try six minutes from time but it was too little too late and proved just a momentary pause in the Leeds celebrations.
