The Panthers Harold Matthews squad experienced mixed results in Friday night's split trial against Parramatta at Patrician Brothers Blacktown, finishing with a win and a loss from two shortened fixtures.
The young Panthers won the first game 8-4 before finding themselves on the wrong end of the same scoreline in the second contest.
Tye Lehson showed plenty of intent early in the first game, taking advantage of a quick play-the-ball to scurry towards the try line. He would be held up, but an attempt at the same play minutes later saw him barge over.
A strong run from Tate Crainfield soon drew a penalty for the Panthers, who marched up-field and sent a charging Aiafi Pomale over for their second try of the game.
Their lead was reduced to four when Parramatta's left centre surged over a couple of defenders to score but Penrith held on for the 8-4 victory.
The Panthers opened the second game in strong fashion and scored the first try when a looping ball from Jake Hay sent Tyler Vanosloski over in the corner.
Parramatta fought their way back into the contest though, with their number 12 dancing around a few defenders before straightening to score under the posts.
The Eels then secured the 8-4 result with a determined effort from their number 25.
The final Panthers Harold Matthews squad will be announced in the coming days as preparations begin for their opening fixture against Sydney Roosters at Panthers Stadium on Saturday 9 February.
