A scarcely believable 47-run last wicket partnership featuring three sixes in four balls to win the game has seen Newcastle Blasters qualify for the Sixers Conference Final of the Men’s Plan B Regional Bash T20 competition.

It came a day after the Blasters' Women's Regional Bash side was knocked without a ball being bowled – Coffs Coast going through as the higher-ranked team after rain forced a washout of the round on Saturday.

On Sunday Teenage No.11 Aidan Cahill joined middle order batsman Mitchell Lole at 9-60 chasing Coffs Coast Chargers' 101 under threatening skies at Oxley Oval on Sunday.

What transpired over the next few overs of madness from the two 18-year-olds will live long in the memory of those who witnessed it.

From a seemingly impossible position, Cahill began swinging with Lole playing the support act to get the Blasters home.

The rain held off long enough on Sunday for Cahill to pepper a nearby school and busy Pacific Drive with sixes - hitting a passing car with one lusty blow - to score a frenzied 29 from just 11 balls.

He brought up the most unlikely of victories with three maximums in four balls in the 19th over, with the composed Lole remaining undefeated on 29 from 23 balls.

The assault was so ferocious the Blasters still had seven balls in hand when the winning six was struck. 

Instead of packing up their campaign, the Blasters will now head to the SCG for the four-team final as winners of Sixers Pool 1.

Earlier in the day, the Chargers beat Northern Rivers Rock and the Blasters accounted for Macquarie Coast Stingers to set up a memorable final.

"The Chargers bowled beautifully and look to have the game won, but they (Cahill and Lole) just went berserk," Regional Bash administrator David Redden said.

"Aidan can bat but it was still an incredible performance considering where the game was at."

The Chargers' 101 on a pitch producing tennis ball bounce looked more than enough as former golf pro Richie Gallichan (3-16 from 4 overs) went about dismantling Newcastle's innings.

The Blasters were 7-43, 8-50 and finally dead and buried – or so it seemed – at 9-60.

While Lole and Cahill were swamped by delirious teammates after the winning runs were hit, there was also high praise for off-spinner Nick Foster, who earlier captured 4-9 to put the brakes on the Chargers' innings.
