Ben Barba scored twice as St Helens further strengthened their grip at the top of the table with a 26-4 win over Hull KR.
The damage was done by half-time as Ryan Morgan, James Roby and Barba all scored to establish an 18-0 lead.
Although Junior Vaivai responded after the break for the Robins, a Mark Percival try and spectacular length of the field effort from Barba secured the win for Justin Holbrook’s side.
