Askern held on to third spot in the Central Midlands League North Division table following their 4-0 derby win against Thorne Colliery at Moorends Welfare.
The game between two of the most improved sides in the CML failed to serve up a goal in the first half.
But Thorne’s hopes of closing to within a point of their Doncaster rivals, with two games in hand, suffered an early blow within five minutes of the restart when Tony Hattersley broke the deadlock.
They remained into contention until the last 15 minutes before Luke Willliams, Ben Wilkinson and Kyle Downing all found the target to put the result beyond doubt.
Harworth Colliery retained top spot with a convincing 5-1 win over Dronfield Town Reserves.
Colliery always looked to be on course for their eighth win in nine starts and led 3-0 at the break.
Jordan Hatton and Lee Edmundson both struck in the first 20 minutes with the latter also notching a second four minutes from the break.
Lee Holmes and Sam Caygill kept the goals flowing in the second half during which Dronfield scored their consolation.
Brad Maddison laid the foundations for AFC Bentley’s 6-0 win at second-bottom Welbeck Lions.
The in-form Maddison scored four of the Bentley goals as they claimed their fifth win to climb into fifth spot. Jake White and Zack King also chipped in to complete the rout.
Collingham won 4-1 against Brodsworth Welfare, who continue to find it tough going.
Welfare had to settle for a consolation by Kieron Bridges as they slumped to a seventh defeat in ten starts.
The home side struggled to contain Marlon Grundy, who scored all but one of the Collingham goals.
Harworth Colliery Reserves held on to fifth spot in League One after returning to winning ways with a 4-0 victory over visiting Radford Reserves.
Simon Byers bagged a brace for Harworth as they ended a run of four successive defeats, with Mick Wibberley and Tom Sowden sharing the other two goals.
