Mark Percival's 22-point haul ensured St Helens defeated Catalans Dragons 46-28 in a frenetic Super League clash.
The England centre kicked nine goals and went over for the decisive score in the closing stages.
The result was only made certain late on as Saints steamed over for three tries in six minutes.
Steve McNamara's Dragons were excellent value for the 28 points they plundered and but for a final-quarter collapse could have taken the win themselves.
St Helens put in a below-par first-half display but still had their noses in front at 20-18 and had enough in the tank to eventually steer clear of the plucky Frenchmen.
The Dragons scrum-half, Luke Walsh, put in an outstanding display against his old employers and had a hand in three Catalans tries, including a solo effort of his own.
