The embarrassment of Penrith's round one humiliation was a distant memory as the Panthers stunned Parramatta in a 20-6 NRL rugby league upset.
Crushed 42-8 by Newcastle on their home turf only last Sunday, Penrith found form in the short trip down the M4, running in three tries to one.
The Panthers were never headed as they jumped out of the gate with an early David Simmons try, halfback Luke Walsh the perfect puppeteer with a sublime kicking game as Lachlan Coote and Michael Jennings found a spark that wasn't there in round one.
Coote and Michael Gordon scored the other four-pointers for the visitors either side of halftime, with Parramatta's solo effort coming via Matt Keating nine minutes from time as he capitalised on a Jarryd Hayne offload.
As striking as Penrith's turnaround was, it was shaded by Parramatta's sudden loss of form - the promise of a new era under coach Stephen Kearney evaporating in a drab 80-minute display.
