Mark Percival scored his second hat-trick of the season as St Helens defeated Warrington 30-12.
Percival scored in the first-half, helping Saints to an 8-6 lead after a Danny Richardson penalty nudged them ahead despite Toby King responding for the hosts.
But James Roby scored his 99th Saints try in the second-half, before Percival completed his hat-trick and Richardson scored late on to secure the win, despite Harvey Livett responding for the hosts.
