Rowley left Saints on Thursday after less than a year in the role and with the team out of form. Jack Welsby got Saints off the mark, and although Bevan French responded soon after, Jacob Douglas restored the visitors' lead. Victory for Wigan moved them level with Super League leaders Leeds Rhinos on 30 points, but Wakefield's big win against Castleford meant the Warriors dropped a place to third in the table. Meanwhile, St Helens have now lost seven of their past 11 games in all competitions.
