Sydney Roosters’ big-money off-season signings finally hit their straps on Monday and it was Parramatta that bore the brunt, the home side inflicting a record 50-0 win over Parramatta at Allianz Stadium.

Sonny Bill Williams and Michael Jennings both scored tries for the Roosters and Roger Tuivasa-Sheck bagged a hat-trick as the hosts ran in nine unanswered four-pointers.

James Maloney maintained his good form since his arrival from the Warriors, kicking seven goals as the Roosters held a team scoreless for a second successive week after beating Brisbane 8-0 last Saturday.

Ricky Stuart said after being appointed it would take time to turn the Eels around and his words look to be prophetic as he experienced the biggest defeat of his long coaching career in front of a crowd of just over 18,000.

Jared Waerea-Hargreaves opened the scoring after 12 minutes when he powered over after Parramatta winger Vai Tautai fumbled Mitchell Pearce’s teasing kick, before Williams added his second of the season.

Tautai’s defensive frailties were again exposed by Pearce when he found Tuivasa-Sheck with a well-weighted kick and the winger acrobatically climbed above the Eels wide man to break his scoring duck.

Tuivasa-Sheck didn’t have to wait long to double his career tally as the Roosters once again roasted the Eels’ right-flank to score a fourth try five minutes before halftime.

The second half saw the Eels find good field position but two scoring opportunities were squandered when Ben Roberts twice knocked on from dummy-half.

Their sloppy play was punished in ruthless fashion when Jennings opened his account for the club in the right corner five minutes after the restart.

That try opened the floodgates as the Eels capitulated, conceding four tries in the final 16 minutes as Tuivasa-Shek completed his treble before Daniel Mortimer and Daniel Tupou got in on the act.
