Meanwhile, Picola United has been headed in the opposite direction and is embroiled in a dogfight for its once secure finals status.
In a match-up of winless outfits, Mathoura was several levels above Blighty, rolling to a comfortable 49-21 victory away at Blighty Recreation Reserve.
Mathoura capitalised on early opportunities to set the tone for the clash with a strong first quarter, its defence particularly firing in the 11-5 term.
The trend continued in the second and the Timbercutters had comfortable control of the game, 24-10 at half-time.
The second half brought more of the same as Mathoura continued to surge away to a maiden win.
The Timbercutters are likely to avoid finishing bottom of the table, potentially dooming Blighty to a winless year.
Picola United v Katandra
A face-off with the fourth-placed Kats was always going to be a challenge for Picola United, but regardless, a sixth consecutive defeat looks to be potentially devastating in the context of its season.
The Blues were a step behind throughout the contest, only putting up five goals in the opening term to trail by eight at the first break.
Things levelled out in the second, Picola only losing the term by one, but Katandra kicked fully clear after half-time to run away with the result 56-34.
Once a lock for finals, Rennie, on a four-game winning run of its own, is now level on points with Picola, the Blues holding on to eighth by percentage.
Picola needs to turn things around quickly and has a good shot at doing so as it takes on lower-table Strathmerton away this weekend, while rival Rennie has a tough assignment hosting Deniliquin Rovers.
