Kevin Sinfield scored a personal tally of 16 points as Leeds Rhinos ran away with the game, finishing 40-12 winners in the south of France against Catalan Dragons.
England captain Sinfield, who earlier in the week had been ruled out of the game with an ankle injury by his coach, turned in a man of the match performance with a try and six conversions from as many attempts.
Tries from Joel Moon, Brett Delaney, Tom Briscoe, Carl Ablett and a double from Ryan Hall ensured the rout. Catalan had consolation tries from Oldfield and Baile, which Barthau converted.
Winger Richard Owen scored a hat-trick of tries as Castleford made history with their first away win over Hull KR in the Super League era to go joint top of the table after three rounds.
The in-form Tigers scored five tries to two in a 30-10 success to end their 20-year wait for a win at Craven Park as they continue to demonstrate there is life after Rangi Chase.
The Robins had no answer to their visitors' sublime offload game, in which loose forward Grant Millington particularly excelled, but Castleford coach Daryl Powell will be especially delighted with his side's tireless defence.
Widnes staged a dramatic late fightback to snatch a 22-20 victory against Huddersfield Giants.
Joe Mellor and Rhys Hanbury scored in the closing minutes at the Select Security Stadium as the Giants, last season's League Leaders' Shield winners, surrendered a strong position for a second game in succession.
