In a potential early finals preview at CommBank Stadium on Sunday, the Tigers grittily secured a third consecutive win for the first time to boost their record to 5-2.
The result means the Tigers just need one more victory in their final four games to secure a winning record, which would all but guarantee a maiden finals berth.
It's a significant feat for the club, who entered this season as back-to-back wooden spooners before hiring coach Craig Sandercock and bringing in 13 new players for the campaign.
Even without representative captain Kezie Apps (leg) and star winger Emily Bass (calf), the Tigers raced out of the gates as halfback Raecene McGregor provided a pinpoint kick to fullback Caitlin Turnbull before winger Lily Rogan scurried across the line twice.
The Warriors clicked into gear though, scoring three tries in six minutes to close the deficit to 16-12 at the break.
The Tigers opened up some breathing room through teenager Namoe Gesa before New Zealand winger Tysha Ikenasio and lock Kaiyah Atai crossed to level scores.
But similarly to last round, interchange Faythe Manera burrowed over for the game-winning four-pointer.
"(I) give all credit to our coach and the recruitment ... (They've) just transferred their knowledge of footy," prop Sarah Togatuki told the Nine Network.
"It (brings) that belief, and it's really inspired this group."
At McDonald Jones Stadium, a second-half sin bin hurt the Knights as Canberra surged home to overcome Newcastle 25-18.
Fresh off manufacturing the upset of the season with a 28-4 demolition of defending premiers Brisbane, the Raiders entered Sunday's clash looking to boost their hopes of making the finals for the first time.
But the visitors looked a shadow of themselves to start, as ill-discipline cost them three of the four opening tries.
Knights centre Sidney Taylor's 47th-minute sin bin for a hip drop tackle on fullback Sheridan Gallagher flipped the game on its head though, as wingers Mackenzie Wiki and Elise Simpson dived over.
Even once she returned, Raiders prop Sophie Holyman crossed, but Newcastle centre Tenika Willison muscled over to level scores.
Halfback Zahara Temara coolly slotted a field goal in the 66th minute before Holyman sealed the victory, helping the Green Machine (4-3) move two points clear of their seventh-placed opponents.
