Penrith's Matt Moylan kicked a field goal late in the game to help the Panthers score an 11-10 win over Manly in their National Rugby League game at Brookvale Oval.
Manly's first loss in three games left it joint last on points with Parramatta.
Fullback Brett Stewart appeared to have a mortgage on star billing after scoring two tries to become Manly's outright all-time leading try-scorer.
The Panthers trailed for 70 minutes of the game, but Moylan kicked a game-levelling penalty with just under eight minutes to go and then landed a 38-metre field goal, inside the last six minutes.
Feleti Mateo and Daly Cherry-Evans missed field goal attempts inside the last three minutes for Manly, who were outscored 7-nil in the second half.
Although Josh Dugan appears to have the inside running for the New South Wales Origin full-back spot, Stewart and Moylan both showed they have the class to step in if required.
Tied on 151 tries with former teammate Steve Menzies, 30-year-old Stewart took just four minutes to claim the outright Manly record with a trademark piece of support play after five-eighth Tom Symonds made a bust.
He pulled further ahead of Menzies in the 23rd minute when he managed to ground the ball for a second four-pointer despite having three defenders around him.
Melbourne, St George-Illawarra, Brisbane and North Queensland top the NRL standings with 14 points, the Warriors are 8th with 10 points, while Penrith are just behind them with 10 points.
