Louie McCarthy-Scarsbrook turned in a man of the match performance against his old club London Broncos as St Helens boosted their top four play-off ambitions in the Stobart Super League with a 30-0 victory.
Skipper Paul Wellens and Mark Flanagan each scored two tries for Saints in the convincing win. The home side's other touchdowns came from Tony Puletua and Anthony Laffranchi in a game which saw them just 10-0 ahead at the break.
Saints acting boss Mike Rush was delighted with McCarthy-Scarsbrook's all-action display. He said: "Louie was my man of the match and produced plenty of energy against his old team. He has great speed for a front rower. At times he chances his arm with offloads but he was outstanding tonight."
Rush added: "Mark Flanagan also had his best game for the club and Paul Wellens was rewarded for his support play with two tries. He must only be a year off 40 but is still punishing them.
"There were 25 penalties in the game and that's a lot to cope with."
London boss Tony Rea, whose side had won their previous three matches, was understandably disappointed by his team's failure to trouble the scoreboard.
Rea said: "We played like a collection of individuals at times and that was reflected in the final scoreline.
"Kieran Dixon tried his heart out but there are highs and lows in all games. We had too many lows tonight."
