Chris Sandow pulled the strings and Jarryd Hayne bagged a hat-trick as the Eels strolled past a pedestrian Warriors outfit 40-10 at Parramatta Stadium on Saturday evening.

Showing some early signs of improvement under new coach Ricky Stuart after taking the wooden spoon last season, the Eels ran in seven tries to two to open their 2013 campaign in style.

Hayne's second and third tries were as simple as you like, three minutes apart late in the second half as the hosts slammed the door on what looked like it could be a Warriors comeback.

The New Zealanders, trailing 18-0 after the break, put on two four-pointers inside the first quarter-hour of the second half through Jacob Lillyman and former Storm centre Dane Nielsen.

But defensive lapses killed the Warriors as Ken Sio dived over just after the hour mark before the "Hayne Plane" made its second and third appearances of the season.

Sio then drove the final nail into the Warriors' coffin with another diving try on the left flank in the shadows of full-time.

Sandow, who scored a try and was denied a second as he converted six of seven, was especially impressive in the first game of his sophomore season at Parramatta after a disappointing first year in which he lacked fitness and form.

His Warriors counterpart Shaun Johnson was a welcome addition to the visiting side despite sustaining a preseason arm injury and looking in doubt to start the season in round one.

Eels: 40 (J Hayne 3, K Sio 2, C Sandow, M Ryan tries; Sandow 6/7 conversions)

Warriors: 10 (J Lillyman, D Nielsen tries; S Johnson 1/2 conversions)
