Minor premiers Hamilton-Wickham will meet second-placed Toronto at No.1 Sportsground across Saturday and Sunday after they knocked out fourth-placed Merewether and third-placed Charlestown respectively.

It is believed to be the first time Hamwicks and Toronto will have played against each other in a first-grade final.

Over the weekend Hamwicks easily defended 8-295 and dismissed Merewether for 122 at Passmore Oval while Toronto's 222 proved too many for Charlestown, who were bowled out for 84 at No.1 Sportsground.

Overnight storms Saturday impacted both pitches, delayed the start of play on day two at each venue and saw overs lost.

Best performers for Hamwicks were Sam Webber (3-6 off 10 overs) and Dave Stevenson (79) while Griffin Lea (5-19 off 16 overs) and Corey Brown (70) were the pick for Toronto.

Hamwicks, premiers in 2016-17, are now looking to add the two-day crown to their Tom Locker Cup one-day title from earlier this summer.

"It's great to be there again and our boys have played well all year so we're looking forward to it," Hamwicks captain Matt Webber said.

"The most pleasing thing about it [semi-final win] was that 11 guys contributed something. Everyone scored runs, everyone took wickets and everyone fielded well.

"Obviously we had the best of the conditions but it was an all-round team effort."

Toronto last made a decider in 2008-09 and skipper Adrian Chad described his side's semi-final showing as "clinical".

"It was a pretty clinical performance from us, which is very pleasing as a captain," Chad said.

"Corey Brown really set it up perfectly [with the bat] and after the first five or 10 overs we knew that 200 or 220 would be a good score.

"Grif [Lea] bowled really well again and his last seven weeks have been outstanding. Plus we just caught everything. We're really pumped to make it through."

Merewether, who had Josh Geary score 50 and Tim O'Neill take 2-101 off 38 overs, fall short of last year's grand final appearance.

"Congratulations to Matt [Webber] and the Hamwicks boys," Merewether captain Simon Moore said.

"The storm hit on Saturday night and the wet wicket didn't help, but they were still the better team and deserved the win.

"Still very proud of our boys and their efforts."

T20 winners and club champions Charlestown, who had Sashreeka Pussegolla clinch 4-57 off 25 overs and Aaron Payne top score with an unbeaten 33, matched last year's semi-final loss.

"It was a frustrating day [Sunday] because of the conditions, but they deserved to go through," Charlestown skipper Jed Dickson said.

"Our young squad will only keep improving."

GRAND FINAL: Hamilton-Wickham (1) v Toronto (2) at No.1 Sportsground on Saturday and Sunday.
