The top clubs in Illawarra and South Coast cricket are just one win away from the final with the semi-finals in both competitions this weekend.
Keira were unbeaten in the 18-round Illawarra one-day season and take on Corrimal, who finished fourth in their return to first grade.
The Cougars will start as outsiders at North Dalton Park, but have Ben Rabjohns in great form with the ball, while skipper Rob Fisher (86) and Joe McDevitt (73) were outstanding in their final-round win over Northern Districts.
Defending one-day champions Helensburgh claimed second spot from Wollongong with the sides to meet in the other semi-final at Figtree Oval.
Keira and the Burgh need only a "losing draw" - not be bowled out if they bat second - to advance to the final.
The losing draw for the finals has been heavily criticised and Wollongong and Corrimal will likely be wanting to counter it by winning the toss and bowling first.
Meanwhile, South Coast minor premiers Lake Illawarra and second-placed Oak Flats have been the top teams all season, but face two dangerous in-form opponents in their semi-finals.
Lake Illawarra take on Gerringong-Jamberoo at Howard Fowles Oval, demonstrating the success of the merger of Gerringong and Jamberoo in first grade this season.
The Lakers are back to full strength for the first time since having four players suspended in January, while Gerringong-Jamberoo have kept improving and in skipper David Reid and strike bowler Scott Adams have two of the competition's best players.
Meanwhile, Shellharbour will play in their first top- grade semi-final since 1998 against Oak Flats at Geoff Shaw Oval.
Shellharbour skipper Ben Mitchell said his side are capable of an upset and are in good form following a thumping win over The Rail in the final round.
Oak Flats skipper Ryan Chatterton believes his team have the big-match experience.
"We've got a lot of players who have played semi-finals and finals and this should work in our favour," Chatterton said.
"Shellharbour have two really good players [Mitchell and Brynley Richards] but we think we have a stronger overall team."
The first grade Illawarra one-day semi-finals begin 10.30am, while the South Coast semis are today and tomorrow from 11am.
