After securing themselves a finals spot in the last round of the season, Natimuk have since shown their strength and look likely to cause problems for Brimpaen in A Special's preliminary final at the weekend.
Natimuk have assembled a full-strength team at the right time of the Central Wimmera Tennis Association season.
They fought out a close two-set victory against Central Park Blue in their semi-final, with the women's line dominating. Cheryl Sudholz, Lana Brown and Holly Smith each won their three sets to propel Natimuk into the preliminary final.
Brimpaen meanwhile came agonisingly short of securing themselves a spot in the grand final with a 8-88 to 6-85 loss against Central Park Red, and now have to do things the hard way.
The key for Brimpaen will be to break even with Natimuk's women's side and press their advantage in the men's department.
In A Grade, Horsham Lawn cruised past Haven in the semis and will be trying to upset Central Park this week.
Central Park slipped up against St Michael's in the first semi-final in just their second loss for the season.
They will be desperate to bounce back to avoid a premature finals exit.
Lawn's Renae Maher and Kelvin Crutch both enter the contest in good form after three-set wins in the previous round.
In B Special, Drung South will be determined to bounce back from their wild loss against Natimuk in the first semi-final, when the scores were tied after regular play. The minor premiers take on Horsham Lawn.
