Parramatta's stunning second half of the NRL season has continued with Penrith brushed aside 48-6 in ruthless fashion at Parramatta Stadium.

Coming into the game on the back of six successive victories, the Eels made easy work of their west Sydney rivals in a performance that yielded eight tries.

Daniel Mortimer scored his first ever hat-trick and veteran winger Luke Burt grabbed two tries and kicked eight goals with Matthew Keating, Fuifui Moimoi and Joel Reddy also crossing in a result that almost certainly ends the Panthers' season.

Penrith went into the game sitting one place above the Eels in eighth spot, but with pre-match talk surrounding ways to stop Jarryd Hayne they failed miserably as the brilliant fullback once again produced a performance of the highest quality.

The Eels got off to a dream start with a try from their first set after three minutes from Mortimer.

The young five-eighth reacted quickest and dived onto a loose ball after Jeff Robson's grubber kick bounced fortuitously off the base of the post and wrong-footed Panthers fullback Jarrod Summut.

The Panthers responded well with two try attempts rejected by the video referee before, almost inevitably, Hayne produced something out of nothing to set up Burt for a second four-pointer for the hosts.

Just when it looked as though the move had broken down after a Mortimer pass failed to find an Eels shirt, Nathan Cayless latched onto the loose ball and released Hayne, who dispatched a perfectly-weighted kick that Burt touched down in the corner.

The Panthers enjoyed a sustained spell of possession midway through the half but were unable to find a way past a well-drilled Parramatta defence roared on by a passionate home crowd of 20,237.

Matthew Elliott's side were then made to pay for failing to take their chances when Mortimer scampered over three minutes before the break with Burt firing over his third conversion to make it 18-0 at the interval.

The second half started in a similar manner to the first with the Panthers once again turning the ball over and Parramatta turning it into a try scored to young gun Keating, who sprinted over from 20 metres out four minutes after the restart.

In what was a torrid night for Sammut, the fullback gave away a try to Burt in a moment he will not want to see again in a hurry.

Hayne once again was his tormenter with another perfectly-weighted kick that was wrestled from his grasp in the in-goal area by Burt to give Parramatta an unassailable lead with the winger once again converting in the 53rd minute.

The Eels added two more tries with Mortimer latching onto a wonder pass from Hayne to grab his third for the night 15 minutes from time, before Reddy (74th) and Moimoi (79) added some further gloss to the scoreline.

Maurice Blair scored a late consolation for Penrith after some good work from the tireless Trent Waterhouse and Luke Lewis.

Parramatta coach Daniel Anderson hailed his side's second-half performance and said that his young players were bringing out the best in his older heads.

"In the first half we were a bit reckless, got lucky with some calls but in the second half we were very, very good and scored some wonderful tries," Anderson said.

"We are in the eight but we are not in the playoffs and I said to the players in the sheds that they have more to do next Friday against the Dragons and hopefully beyond.

"We have a young, effervescent group of bubbly players Morts, Jarryd, and players that are young in age and they are bringing out the best in the old hard heads.

"The young blokes are putting the wind up the old blokes."

Panthers coach Matthew Elliott remained upbeat after the game and said errors at crucial times led to his side's downfall.

"It was a weird game from my perspective our poor completion rates meant we didn't give ourselves a chance to compete for the game," he said.

"In attack we dug ourselves a hole by making errors and when we built up some momentum we made mistakes which is what you do when you are tired."
