Tickhill are 22 points adrift of safety with four games to play in the ECB Yorkshire South Premier League following a 137-run defeat at home to Treeton.
Their cause was not helped either by wins for two of their relegation rivals - Aston Hall, who eased past bottom side Sheffield and Phoenix United, and Cleethorpes, who beat third-placed Whitley Hall.
Treeton won the toss and elected to bat first at Alderson Drive.
After reaching 46-2, Archie Ogden and Mohammed Waheed added 71 runs before Ogden left with 84 to his credit.
Waheed was then joined by Sam Drury and the pair shared an unbeaten partnership of 132. Waheed was 76 not out and Drury 51 not out when Treeton closed on 249-3.
Tickhill’s innings was a different matter altogether as they were reduced to 28-7.
Greg Norton clean bowled the first four batsmen and Vinnie Ogden claimed the next three, clean bowling two.
A late rally by the tailenders saw Usman Muzaffar score 31 not out and improve the final total to 112 all out. Norton took 4-43 and Ogden 3-27.
