WANTIRNA South set up a preliminary final date against North Ringwood in the RDCA Lindsay Trollope Shield on Sunday.
The Devils beat Ainslie Park at Ainslie Park Reserve in the elimination final, posting 9-307 on Saturday and then holding steady to overcome a strong Parkers batting order on Sunday, bowling them out for 233.
Devils captain Matt King said his bowlers had to work for their wickets after the Parkers reached tea on 3-147 from 39 overs.
"Ainslie Park plays an unorthodox style of cricket so it's difficult to set fields and bowl to them," he said.
"Our bowlers spent the early overs having a crack at the batsmen so we were bowling both sides of the wicket and getting hit all around the park. But after tea we started concentrating on bowling to our game plan and then it all went out way."
Wayne Ross took 6-31 as the Parkers got to 5-217, only to lose 5-16 to be bowled out.
"Having 300 on the board meant they had to bat well for all 80 overs so we only needed to bowl well for a 10-15 over block and we would get on top but it wasn't all smooth sailing for us."
King said the Devils faced a tough game against North Ringwood which lost the qualifying final to South Croydon and has lost four straight matches.
South Croydon beat North Ringwood by three runs with nine balls remaining.
Defending 4-198, North Ringwood was in all sorts of trouble early at 4-35 with Travis Degenhardt (5-59) back in form. Michael Scott (104) and Luke McPhie (37) then put on 113 for the fifth wicket to get the score to 5-148. The Bulls then lost their sixth wicket at 170 before the Bulldogs took 4-25 to win.
The winner of the preliminary final will face South Croydon in the grand final the following weekend.
"North Ringwood is another team who beat us in a close game earlier this season," King said.
"They are struggling for momentum so if we can get some runs on the board and then put them under pressure we will be on the right track.
"We will need to back ourselves and play like we have the whole season."
