Penrith overcame half-time loss half-naked Nathan Clearley to win the first time in 2019, with a fast score of 15-12 at Sea Eagles on Thursday night.
The win was built on the inspired shock of the young striker Liam Martin, called from the reserve list to the home side on the day of the match, when the key man Viliame Kikau was excluded due to illness.
Playing in his sixth NRL game, Martin tried his first win and played a big role, setting one try and scoring the other as the Panthers were twice in a row.
Returning from a suspension in one match, the rejected Blues pole James Malonei had the greatest effort of the year in Cleary's absence.
Manley, however, showed a little more positive signs than in their loss in the 11th round at Titan's home, with only props by Addin Fonua-Blake and Martin Taupau who will probably find them in the front foot.
Despite having owned 57%, Sea Eagles generally looked like deprived of ideas in the attack 20, and their striking match was poor.
Penrith had his own difficulty in the red zone of the opposition and after refusing several blows to the penalty goal near the line, he eventually scored two points in the 21st minute.
After struggling to turn the chances close to the line, they instead redeemed their half when Martin split the line and found Dilan Edwards's support to make it 8-0.
The only additional opening result of 40 came a few seconds before the siren when Malonei decided to throw a 38-meter mark in order to score 9-0 at break.
After the first half, which easily led to the wrong container, there was another 15 minutes in the second half, where Jarome Luai and Jack Gosievski marched in 10 minutes.
Shortly thereafter, Tirell Fuimaono was put on a shoulder in the fork of Curtis Sironen.
Penrith reached a seemingly unbeatable advantage when Brendan Elliot poured a grubber, and Martin made a deserved attempt and a 15-lead advantage with less than 15 minutes to play.
The newest half of Cade Cust set bench for Manase Fain bench with some nice legs to give Manley a thin hope, and then Cust crossed over in the last five minutes to set the end of the stand.
The revived Sea Eagles dropped some late form on the Panthers, but it was too late and could not win the clock.
On the back of the two consecutive victories, the Panthers now move in the 13th round with Roosters, and confidence is growing. On the contrary, Manley has now lost three of the last four and faces a long trip to North Queensland after Origin I.
