A final-round match between Koroit Blue and Mortlake Blue will decide which of the two plays Western District Bowls Division finals in 2020.
Fourth-ranked Koroit will host fifth-placed Mortlake on Saturday.
Mortlake Blue, which kept its finals chances alive with a 69-49 win over Warrnambool Blue in the penultimate round, sits just two points below Koroit.
Mortlake Blue skipper George Draffen said it would go down-to-the-wire.
"There's every chance the winner goes through and the loser is out," he said.
"We are pretty excited. It is a tough ask, Koroit at Koroit, but if I said at the start of the season we'd be in with a chance to be in finals by winning the last game, you'd be happy to take that."
Draffen said Mortlake Blue would go in as underdogs, given its opponent's recent finals appearances.
"We are both under pressure but they have been perennial finalists and premiership contenders the last few years so they are under more pressure," he said.
"At the start of the year they would've expected to be top-two or three.
"We played them early in the year at Mortlake and they beat us narrowly.
"We really have to be at our best and hope things run our way a little bit. It would be nice to stay in contention early and not have a rink blowout."
Draffen said Mortlake would regain skipper Colin Goldsworthy, who has been away in Hawaii, for the clash.
The experienced leader praised the new-look pennant for providing closer contests this season.
"The 12-a-side in division one is a good thing for the competition," he said.
"It's a lot more even and pretty competitive. Home ground is a fair advantage, there's more variety in the greens than in the past."
Warrnambool Gold, City Memorial Red and City Memorial Gold have locked in their finals places.
In other round 13 games, Koroit Blue defeated Dennington Jets 67-58, Port Fairy Red surprised City Memorial Gold 76-62, City Memorial Red was too strong for Terang Green 78-51 and Warrnambool Gold trounced Timboon Gold 82-48.
