Hatfield Town eased their relegation fears with a 101-run win at Premier Division bottom side Barnby Dun.
The hosts had given themselves hope of avoiding the drop with two wins from their last three games going into Saturday’s derby clash.
But they came up short against a Hatfield side who posted a solid score and then followed it up with the ball.
Ellis Pattison top scored with 80 and Connah Pattison carried his bat for 67 as Town posted 230-5.
In reply only Carl Norris (36) provided any resistance as Barnby were dismissed for 129.
James Winstanley (4-32) and Kevin Marshall (3-29) did the damage.
Hatfield have an 11-point safety cushion, with the second relegation spot now occupied by Hooton Pagnell following their 32-run defeat at home to Askern Welfare.
Mark Ilman (78) and Aaron Gillies (57) were the mainstays in Welfare’s 235-6.
In reply Hooton managed 203 all out as David Longley claimed 5-43 and Sachira Madapatha took 3-41.
Rossington Main moved out of the drop zone following a six wicket win at home to fellow strugglers Old Sharlston.
Roy Nelson’s 4-35 helped restrict the visitors to 189-9.
Greg Mann then hit an unbeaten 71 and Joel Evans was 56 not out at the close as Rossington reached their target in 40.1 overs.
Long-time Division Two leaders Brodsworth Main are wobbling with the finish line in sight.
They have now suffered back-to-back defeats after losing by four wickets to Darton - one of three sides who remain on their coattails.
William Drury top scored with 67 in Main’s 155 all out.
David Merryweather then took 4-30 but Darton completed the chase in 46.4 overs.
The Division Three table makes poor reading for Doncaster clubs with Bullcroft Main and Bentley Colliery all but consigned to relegation.
Main, without a win all season, lost by five wickets at Kilnhurst Colliery on Saturday, while Bentley lost by ten wickets at Thurnscoe.
