St Helens suffered a second shock Super League defeat in as many weeks as a late penalty try earned Wakefield Trinity a 16-12 victory at the Totally Wicked Stadium.
A week on from their 24-16 loss at Leigh Centurions, Saints looked to have avoided another surprising setback on Friday when they came from 10 points down to lead - Mark Percival crossing twice after the interval.
However, Percival's failure to convert his own tries and a first-half score from Ryan Morgan ultimately proved costly.
Wakefield had lost their last nine Super League matches against Saints, but snatched victory on this occasion thanks to Jacob Miller being pulled back by Danny Richardson as he looked to dive on Sam Williams' grubber kick under the posts.
The video referee awarded a penalty try, converted by Williams, and Trinity held on to claim their first points of the season.
Williams had earlier kicked two penalties either side of converting a spectacular try from Mason Caton-Brown, who finished acrobatically in the right-hand corner.
Reigning champions Wigan Warriors beat Leigh 20-0 at the DW Stadium in Friday's other fixture to continue their perfect start to the season.
Anthony Gelling scored two tries for Shaun Wane's men, while George Williams also touched down and Morgan Escare kicked four goals.
