The Parramatta first grade side rode two big partnerships to a huge total in the first day of its NSW Premier Cricket clash with Penrith.
In the first two-day match of the season, Parramatta took advantage of dry conditions and a great batting wicket to set challenging target.
New opening pair of Tim Ward (90) and Will Affleck (77) set a perfect platform for Parramatta with a 172-run partnership before both fell in quick succession.
It brought captain Nick Bertus and regular opener Brenton Cherry to the crease and the duo continued to torment the Penrith bowlers.
In a 119-run partnership, Bertus hit 65 off 79 balls before his dismissal, while Cherry celebrated his move to number four in the batting order with an unbeaten 102 off 117 balls.
Parramatta lost several late wickets cheaply while chasing quick runs before Bertus declared the innings closed at 6-398.
Ben Martin then struck with the ball, leaving Penrith 1-6 after five overs to close out a strong day at Old Kings Oval.
