Regan Grace scored twice as Super League leaders St Helens ran in five tries to defeat struggling Catalans Dragons 26-12.

Saints put on 66 and 60 points in beating Huddersfield Giants and Salford Red Devils in their previous two fixtures and, although the scoreline on Thursday was more modest, Justin Holbrook's side had too much quality at the Totally Wicked Stadium.

It was a tough ask for the visitors from the moment Tommy Makinson kicked inside for Jonny Lomax to open the scoring, and provider turned scorer for Saints' second in the 14th minute.

Brayden Wiliame responded for Catalans after it was judged he had grounded the ball, but Morgan Knowles wormed his way through shortly after as the hosts led 16-4 at the break.

Quick hands from Saints saw Grace go over for his first early in the second half with Theo Fages and Mark Percival influential in the build-up.

Jodie Broughton reduced the arrears, but neat play down the left saw Grace cross for a second time and Lewis Tierney's late score was little more than a consolation for a Catalans who remain second bottom.
