Hanging Heaton will meet Wakefield Thornes in Sunday's Yorkshire Premier League Play-off final at Headingley.
They overpowered the Hunters Yorkshire League North champion York at Headingley while Thornes, who became the first winners of the White Rose Trophy in Abu Dhabi last year, beat Great Ayton from the North Yorkshire South Durham League by 187 runs at Scarborough by 183 runs.
Hanging Heaton were put in to bat and soon stamped their authority on the match as they compiled the highest play-off score to date of 312-4.
They made that total despite losing their prolific left-hander Nick Connolly for just 11 when he was trapped lbw by young Yorkshire all-rounder Matthew Waite.
Skipper Gary Fellows and Richard Foster picked up the tempo. They took the total on to 104 before both fell to lbw decisions on the same score. Fellows was looking set for another big individual score when he became Waite's second victim.
Foster was an early victim for Yorkshire's Jack Leaning when he entered the attack.
If the Hanging Heaton supporters were worried that the innings was going to falter those fears were soon calmed by the fourth-wicket pair of Callum Geldart and Joe Fraser.
It was initially Fraser who took the attack to the bowlers as the runs started to flow.
Fraser struck a six and six fours and looked set for a deserved half-century when a ball from Leaning reared up and was caught for 48. His partnership with Geldart garnered a valuable 100 runs. Geldart, who has the ability to mix orthodox with improvisation, was taking a liking to the York bowling.
James Kean ensured that there was no let up for the wilting York attack. He was quickly into his stride as the two left hander shared an unbroken stand of 108 from 76 balls.
Geldart finished unbeaten on 90 after hitting three sixes and six fours in a thrilling 79-ball knock, while Keen struck three sixes and five fours in his unbeaten 52.
Geldart's confidence was perfectly illustrated when he hit a six off Leaning with a remarkable switch hit.
The York bowling figures reflected the punishment they had been subjected to. Waite finished with 2-88 in 15 overs and Leaning 2-76.
York needed a good start if they were to chase down Hanging Heaton's 311-4 in fading light, but they didn't get one.
Their prolific opener Duncan Snell - the former Woodlands player - was superbly caught at slip by Fraser off Tom Chippendale for 12.
Waite followed him back to the pavilion when he was trapped lbw by David Stiff for nought.
When Yorkshire batsman Jack Leaning skied an attempted pull off Chippendale and was caught by Muhammad Rameez for 22, York were 49-3 with the three big guns all out.
When David Stiff removed Matthew Bell and Tom Brooks in quick succession, York were 61-5 and the writing was on the wall.
Adam McAuley and Charlie Elliott were in no mood to give up without a fight.
McAuley played some attractive shot in his 37, while Elliott was more forceful as he hit three sixes and five fours in his 53.
When both fell to left-arm spinner Muhammad Rameez the end was in sight. Chris Goodair sealed Hanging Heaton's place in the final by dismissing Tom Pringle and Oliver Leedham.
Chippendale was the pick of the bowlers with 3-35 while Stiff finished with 3-55 as York were bowled out for 190 in the 37th over.
David Toft, the player whose century guided Wakefield Thornes to victory over Pudsey St lawrence in last year's play-off final, was in top form again as he guided his side to their second final appearance.
He made a superb 102 as Wakefield Thornes scored 273-7 before bowling out Great Ayton for 90 at Scarborough.
Matthew Jordan (67) and Jared Warner (40) were the other main contributors to the Wakefield Thornes total.
Left-arm spinner Steve Morgan (4-14) and Faisal Irfan (3-14) ensured that Great Ayton's hopes were quickly extinguished.
