Penrith turned back the clock 12 months and smashed some records in the process, thrashing Manly 72-12 at Penrith Stadium on Saturday night.

The scoreline represented both Penrith's biggest ever win and Manly's biggest ever loss.

For good measure, the 28 points scored by winger Amos Roberts, with two tries and ten goals, equals the club record for most points in a game, also held by Ryan Girdler.

Manly's previous worst ever loss was a 61-11 defeat by St George in the club's debut year of 1947.

Penrith's previous biggest ever win was a 60-6 defeat of Wests in 1999, but Saturday night's 13-try effort against a hapless Manly side - who must now be favourites for the wooden spoon - blew that out of the water.

The Panthers have been inconsistent at times this year, but on Saturday night the passes stuck, the tackles were hard and the discipline good in a performance reminiscent of last year's golden run to the premiership.

Coach John Lang said the win cemented the club a spot in the top eight, and although he praised his side's performance, he did so in measured tones, saying a top four spot, and the home final that comes with it, is still far from certain.

"I think we're far from (the top four), but I think we've cemented a spot in the eight and now we want to finish as high as we can," he said.

"The thing that I was really pleased about was that we didn't drop our intensity in our defence when we had the big lead.

"It's probably one of the hardest things I've found over my career as a player and a coach to do - when you've got a game won, it's very easy to drop off and start thinking about next week, but we played the 80 minutes right out."
