Although the Warriors came out of lockdown with a roar, beating the Dragons, they were unable to keep up the pace, when they faced the Panthers.
Down 16-0 at halftime, the Warriors lost to the Penrith Panthers 26-0 at Campbelltown on Friday night.
"We're beating ourselves and we're just not giving ourselves a good enough chance tonight," coach Stephen Kearney said at the aftermatch press conference.
"What the new game is teaching us is that you just can't let a team get away from you and make it really hard for yourselves with errors, kick finishes, penalties. You just make life really difficult for yourself."
This brings the Warriors'record for the season to one win and three losses and leaves them in 12th place in the competition.
The Warriors are in training to play the Cowboys next on June 12 at the Central Coast Stadium.
"The reality is that we missed our jobs tonight, missed our assignment. We get another chance to work on that and fix that next Friday," Kearney says.
