Conisbrough left it late to steal a march on title rivals Houghton Main in a thrilling top of the table clash at St Peter’s Drive.
Wicketkeeper Jack Whittaker held his nerve to make an unbeaten 35 and steer Conisbrough to a narrow two wicket win.
The victory took the home side five points clear at the top and came with just one ball to spare.
More so, the win was only sealed in the extra over that Conisbrough were afforded as a result of bowling out Main in 49 overs.
Houghton batted first and Ian Simon (54) and Peter Colbourne (46) added 75 for the second wicket.
Tanzeel Ali smashed 64 and Ben Dalton added 44 as Main amassed a very respectable 264 all out with an over to spare.
Nicholas Morley, who has impressed following his winter switch from Doncaster Town, snared 5-74 for Conisbrough.
After losing Matthew Barnes without a run on the board, Scott Lowe and Tim Shelley combined superbly to add 139 for the second wicket.
But wickets fell at regular intervals before Whittaker dug his heels in to see Conisbrough to victory in the nick of time, with that wasted over coming back to haunt second placed Houghton.
Callum Honeyman took 5-52 for Main.
Top met bottom when Wath hosted Darfield in the Premier Division - and the result did not go as the form book suggested.
Darfield elected to bat first and Liam Dickinson (32) and Peter Hadfield compiled 104 before Wath’s first success.
Peter Hadfield became the fourth wicket to fall when he departed for an excellent 104.
The visitors’ innings closed at 236-8, with Rob Barlow collecting 3-65.
South African opener Derek Mitchell scored 42 for Wath but the innings lacked the power that had been displayed during the win over Wickersley the previous week.
The hosts meandered to 183-8 at the close, allowing Treeton to overtake them at the top.
Tickhill suffered an agonising three-run defeat to Norton Oakes who won for the first time this season.
Paul Revill (61) and Alex Hibbert (73) compiled an opening stand of 129, helping Norton reach 210-8 from their allotted overs.
Steve Reid (4-50) and Tom Barnett (3-35) starred with the ball for Tickhill.
In reply Tickhill’s first four batsmen were back in the pavilion with just 16 runs between them.
James Stuart (39), Aaron Haycock (44), Barnett (43) and Reid (43no) led the recovery but Tickhill were bowled out for 207 with an over remaining.
