SECOND-placed Denholme triumphed over Shelf, who were third, in one of the most thrilling games of the season in the Bradford & District Evening League.
Jaweed Waheed (37) helped to rescue Shelf from 55-5 to a respectable 126-9, which included five penalty runs for the ball hitting a helmet.
At 38-3, the home side were in trouble and found themselves requiring 50 off the last three overs. Jamie Rowell (40no) and Tom Cummins (47no) continued the recovery but they still needed a seemingly improbable 21 runs off the last over.
With Rowell facing the final ball, he dispatched it over the square-leg boundary for six for Denholme to win the game by one run.
The victory leaves Denholme two points behind leaders Salem Atheltic, who enjoyed a comfortable win over Bingley Congs – with the top two meeting tonight.
At the other end of the table, Thornton moved four points clear of Smart Moves as they restricted their rivals to 108-6, with Hans Randawa (51no) contributing nearly half their score.
Openers Josh Hutchinson (55no) and Scott Richardson (33no) then laid the platform for a nine-wicket success.
Daniel Holah (50no), ably supported by Matthew Lumb (43) and Ben Waller (34), saw John Breare post a very competitive 157-3 against relegation rivals Tong Park Esholt, who replied with 121-6.
Wibsey Park Chapel and Buttershaw St Paul's recorded comfortable wins over Shipley Providence and Keighley respectively to jointly claim top spot in Division Two, taking advantage of Thackley's surprise defeat at Cambing.
Luke Holroyd's 45 and Alan Cuff's not out had helped Thackley to 138-4 but Sajid Khan (43) and Yasir Ali (55no) took up the challenge, dispatching the ball to various parts of the boundary as the home side cantered to a shock seven-wicket win.
Oakworth recorded the highest score of the day, making 201-4 as Brannon Lawn (51no), Adam Smith (46), Jack Hainsworth (41) and Lewis Wrathall (30) all enjoyed themselves on Queensbury's picturesque ground.
James Thompson (53no) did well for the home team, who finished on 125-5.
Indian Panthers and Mayfield enjoyed wins over Stonewhite and Daisy Hill respectively to move up the table.
