Leaders St Helens have finished with a flourish to overcome a stern test from bottom of the table Huddersfield and preserve Super League’s only 100 per cent record.
The Giants, fresh from their first win of the season over champions Wigan, threatened to pull off another shock when they drew level at 12-12 on the back of some enterprising play at John Smith’s Stadium.
But England centre Mark Percival scored the first of his two tries three minutes before half-time to restore Saints’ lead and the table-toppers added another four tries after the break to run out 40-12 winners.
Saints coach Justin Holbrook had the luxury of recalling veteran hooker James Roby after resting him for last week’s win over London Broncos.
The Giants, meanwhile, were without Aaron Murphy, Jake Wardle and Adam O’Brien.
There was no stopping prop Luke Thompson who scored the opening try and Huddersfield opened up invitingly again for loose forward Morgan Knowles to take Roby’s pass and score a second after 22 minutes.
In between, the Giants created a superb try for England winger Jermaine McGillvary and struck again after 25 minutes through former Saints centre Jordan Turner.
Percival touched down from a Jonny Lomax grubber to give the visitors a 16-12 interval lead and Coote nudged them further ahead with a penalty early in the second half before the decisive score came on 53 minutes.
Coote’s attacking kick held up just inside the dead-ball area and when McGillvary lost the ball in the tackle, Percival stretched out a hand to score his second.
When Akuila Uate knocked on, he was instantly punished with Saints scoring from the resultant scrum through Regan Grace before Dominique Peyroux and Lomax adding further tries in the last 12 minutes.
