Wakefield Trinity’s Bill Tupou climbed the Steve Prescott Man of Steel rankings after his superb performance in last week’s win at Leeds Rhinos.
Every Super League game this year will be watched by a member of the judging panel who awards three points to his man of the match, two to the runner-up and one for the game’s third-best player.
After picking up three points last week Tupou and teammate Danny Brough - who earned one point - are among six players on four points.
The two points in last week’s game at Emerald Headingley went to Trinity’s Tom Johnstone.
Castleford Tigers’ Liam Watts is joint-second after collecting three points from his side’s win over Hull KR.
Teammate Paul McShane, who did not score in round four, is also on six points, along with Hull’s Jamie Shaul.
St Helens’ James Roby is the runaway leader, on 11 points.
