Big hitting Birstwith made mince meat of struggling Pateley Bridge to reach the semi-finals of the Nidderdale League Atkinson Swires Cup.
Having smacked 378/7 against West Tanfield in the previous round, Birstwith went even better on Sunday, crashing 435/4 from their 40 overs.
Jon Millward (90) and Tom Croston (98) started the festival of runs before James Riley plundered ten sixes in an incredible 37-ball century.
Dan Riley continued the fun at the other end with an unbeaten 70, while Craig Armitage added 32 from just nine balls.
The bowling figures made difficult reading for Bridge, with captain Tom Simpson conceding 98 runs off his eight overs.
Pateley made a usually competitive 226/2 in response as Colin Chadwick (67no), Nick Shirt (75) and Simpson (53no) all made half centuries.
Birstwith now face Spofforth in the last four after the latter chased 262//6 for the loss of just two wickets against Burton Leonard.
Andrew Bottega made a pivotal 138 in what had looked a difficult chase as Spofforth reached the total with more than five overs in hand.
Pat Gannon also compiled 70 for Spoff on a busy afternoon for the scorekeepers, following half centuries by Sam Crompton (71), Matt Rangeley (65) and Tom Rowlay (75) in the opening innings.
Harrogate Straydogs caused the shock of the quarter finals to set up a last four clash against Helperby, who also defied the odds to progress.
Luke Wilkinson’s four-wicket haul helped The Straydogs bowl Division One title hopefuls Darley out for a mere 133, a total which posed little problems for the second tier outfit.
Despite falling to 10/2, Harry Stothard’s 68 – including six sixes – bagged a six-wicket success with more than 10 overs in hand.
Helperby chased a target of 217 with just two balls spare to knock holders Ouseburn out.
Sam Parker (72), Adam Fisher (61) and Jamie Bryant (58no) put Ouseburn on the way to a competitive total despite Trevor Chobvongodze taking 4-48.
Helperby were staring down the barrel at 100-4 but Dan Marston’s run-a-ball 66 secured a surprise five-wicket win over the league leaders.
