After winning the toss at the 2bm Ground they elected to bat first and, after an early run out, Luke Thomas and Daniel Wood compiled a partnership of 167 for the second wicket, a stand ended when Wood was dismissed for 83.
Thomas dominated the remainder of the innings, before being run out just before the end.
His score of 146 is the highest individual score so far this season. The Cuckney innings closed at 269-five.
After tea, the hosts made steady progress in their pursuit of the 270-run target.
Where two batsmen dominated the first innings, the second was much more of a team affair, George Bacon’s second ball duck being the only failure.
John Terry (38) and Tom Rowe (47) added 67 for the second wicket, then Sam Johnson (48 not out) shared stands of 79 with top scorer Sam Ogrizovic (55) and 61 with Alex King (45 off 25 balls) as the Institute completed a four wicket win with four balls remaining.
Clifton Village took full advantage of Cuckney’s slip-up, recording a four wicket victory over hosts Welbeck Colliery.
The home side won the toss and chose to bat, using a partnership of 141 between Richard Stroh (91) and Andrew Parkin-Coates (66) as the bedrock of their total of 230-8.
Martin Weightman, with 4-64, and Shreyas Iyer, with 3-62, did the most to hold Welbeck back.
The Clifton reply got off to a slow start, slipping to 61-3 before a 59-run partnership between Scott McNeill (48) and Shreyas Iyer got them back on track.
From there Iyer took over, finishing unbeaten on 104 from just 83 balls as the Villagers reached the target with seven overs to spare.
Rolls Royce Leisure sit third in the table just a point behind Cuckney after they recorded a comfortable four wicket win away to Radcliffe-on-Trent.
The visitors won the toss and put their hosts in.
Tom Lungley tormented the home batsmen all innings on his way to seven wickets, while just three Radcliffe players reached double figures.
Robert Sutton’s 37 was the significant contribution as they stumbled to 83-9, with only a 10th wicket stand of 73 between Jacob Deavin-Baker (27) and Jake Fish (54 not out) allowing them to reach 156, Lungley posting 7-30 from 12.4 overs.
Rolls passed the target with eight overs remaining, having lost six wickets, Shaun Levy, carrying his bat for 91, providing the lion’s share of the runs.
No other batsman passed 15 as David Lucas, with 3-28, and Eddie Torr, 3-35, shared the wickets.
In another high-scoring affair at The Fieldings, West Indian Cavaliers prevailed over hosts Mansfield Hosiery Mills.
Cavs skipper Bilal Shafayat called the toss correctly and opted to give the home side the honours. The opening stand was worth 64 when leading bat Gareth Curtis fell to Shafayat for 37.
Tom New joined his brother Matt, at the crease and the pair added 186, Tom becoming the only other wicket to fall in the innings, having scored 87.
Matt finished unbeaten on 102 as the innings closed on 261-2 from the 50 overs.
Keshara Jayasinghe’s 3-64 reduced the Cavaliers reply to 55 for three, Usman Afzaal contributing 30 of those.
Amar Rashid (30) partnered Shafayat to add 70 for the fourth wicket, but the match-winning stand was between Shafayat and Sadiq Hassan.
The pair added 138 runs to remain unbeaten as the Cavs cruised to a six-wicket win.
Hassan finished on 64 not out and Shafayat struck five fours and six sixes on his way to 103 not out at better than a run a ball.
Plumtree welcomed the Nottinghamshire Academy to the PCG and, after Paul Franks called incorrectly, the home side invited their visitors to bat first.
Academy’s woes with the bat continued, only Adam Tillcock (34) and Anuj Dal (31) able to put up any resistance as they combined in a stand of 58.
Wickets fell regularly, however, as the county youngsters posted 136 all out in the 48th over.
Matt Milnes took 4-29 from his 13 overs and Graeme White 4-47 from 13.5 as the destroyers-in-chief.
Academy skipper Franks tried eight bowlers in the chase for wickets, to no avail, Sam Storey (47) and David Bedingham (43 not out) steering the Plums to a seven wicket win inside of 38 overs.
The day’s quickest and most comprehensive victory was achieved at Caythorpe, where Ordsall Bridon skipper Paul van den Heuvel made the correct call at the toss and chose to have first go with the bat.
He and David Fagan made steady progress to 35 before Fagan gave Jim Hindson the charge and the wheels fell off.
Unable to cope with Hindson and his spin twin, George McCaffrey, the innings limped into the 39th over before Bridon were all out for 81, Hindson finishing with figures of 6-21 from 13 overs and McCaffrey claiming 3-16 off nine overs and a ball.
The Caythorpe reply was relatively serene as Hindson (33 not out), pressed into opening in place of the absent Martin Dobson, and James Hawley (34 not out) reached the required total in the 16th over, the match lasting just over half the scheduled overs.
