The Tigers could thank Lachlan Hansen and Robbie Tarrant for their contributions up forward in a 14-point win.
Hansen pulled down an impressive 13 marks and booted three goals in arguably his best performance of the year, while Tarrant was also strong in the air with 11 marks and kicked four majors.
Fellow key-target Ben McKinley struggled to get into the game, but development coach John Lamont praised his effort in crucial contents when the game was in the balance.
Ayden Kennedy's emergence continued with 17 disposals at centre half-back as he signalled his intentions of donning the royal blue and white for the first time. Sam Gibson no doubt has similar ambitions and his 25 possession, two goal effort keeps his name in lights for a possible promotion to the senior list mid-season.
Rookie Brad Mangan was solid in defence and finished with 16 touches, while in the ruck Majak Daw amassed 20 hit-outs.
Ben Speight was a little quieter than last week (12 possessions), while Will Sierakowski's return following an appearance as an emergency for the Kangaroos netted him 11 disposals. Malcolm Lynch had seven touches.
