Six wickets for Sandiacre's Jordison
Sandiacre stretched their lead at the top of the Beechwood Saab Derbyshire Premier League by racing to a nine wicket win over Dunstall thanks to a superb 6-21 from John Jordison.
A thriller at Queen's Park saw Chesterfield finish four short of Ockbrook's total with one wicket left when play was abandoned with two overs to go.
Lullington stayed third despite being on the wrong end of a draw with resurgent Quarndon while Elvaston had the best of a draw with Matlock.
Ilkeston hung on at home to Spondon and A&B's hopes of a win over Alfreton to ease their relegation fears were thwarted by rain.
Sandiacre Town consolidated their lead at the top of the Beechwood Saab Derbyshire Premier League with a crushing defeat of Dunstall who were shot out for just 98.
Jordison was named man of the match for his endeavours while Ryan McFadyean finished with a no less impressive 3-8.
It took James Chapman (46 not out) and Ant Woolley (43 not out) just 19.1 overs to wrap up victory with Dunstall going home empty-handed. Sandiacre's lead at the top is now 31pts.
A deluge with Alfreton struggling on 64 for four cost Alvaston & Boulton an almost certain victory and some very useful points in their bid to avoid the drop.
In the event they had to settle for a haul of 12pts but Dunstall's heavy defeat against Sandiacre was at least some consolation for the eleventh-placed side.
A & B notched up a challenging 247 for eight from their 50 overs with half-centuries for Chris McIlroy (53) and Hassan Adnan (56) and a useful 35 from David Lewis.
Matt Lineker claimed 3-41 for Alfreton. A & B were in total control after the break but rain eventually won the day.
Ilkeston Rutland just managed to hang on against visitors Spondon, closing on a perilous 132 for nine chasing Spondon's modest target of 176 for eight.
Chris Windmill (43 not out) was in fine form for Spondon, his unbeaten knock following good efforts from Oliver Baum (35) and Dave Hartley (31) as Chesney Hughes (4-57) threatened for Ilkeston.
Windmill (5-26) dominated the Ilkeston reply but David Smit's innings of 41 gave his side the breathing space to eventually secure a hard-fought draw.
Quarndon just got the better of title-chasing Lullington Park after posting a solid 222 for seven in a rain-reduced 44 overs.
Rudi Hillerman (3-26) reduced Quarndon to 82 for four but opener Montcin Hodge (54) was still there and was joined in a 67-run stand for the fifth wicket by Muhammad Sultan (56) and further runs from Josh Lowe (36) gave Quarndon a good total to defend.
Matt Dowman (3-40) and Adam Street (3-39) made Lullington's task all the harder after tea, reducing the visitors to 67 for four but a fifth wicket stand of 79 between Jonny Shales (32) and Hillerman (72) gave their side every chance.
But James Ede (2-25) applied the brakes and Lullington were eventually restricted to 207 for eight and a haul of just 11pts.
A dramatic rain-affected match saw Chesterfield fall just four runs short of victory over faltering Ockbrook & Borrowash as time got the better of proceedings at Queens Park.
Ockbrook had earlier stuttered their way to 178 for eight with Brian Gladwin (3-40) giving little away.
Jake Needham (50) and Trevor Smith (43) repaired the early damage of a slump to 24 for two with a third wicket stand of 77 but Ockbrook were probably a few runs short when 40 overs came to an end.
Further interruptions made the match a timed affair but Chesterfield crept towards the winning post thanks to good knocks from James Pipe (40) and Chris Marples (33) but Ockbrook were making their own push for victory through the excellent Lian Wharton (6-47).
The weather had the ultimate say, however, and Chesterfield's reply had reached 175 for nine after 38 overs when old father time intervened.
Elvaston will almost certainly be relegated to Division One come the season's end but they put on a good show against Matlock.
Matt Archer (43), Charlie Ault (37) and Joe Cooke (42) all prospered early on but it was the fine partnership between Paul Birch (66 not out) and Rob Kettlewell (43 not out) that eventually got the scoreboard moving.
Matlock were left chasing a daunting 269 for five but made good progress through Matt Doyle (59), Matt Cluer (66) and Minesh Keshwala (31) but Ian Hall's 4-75 was just good enough to leave the visitors short on 258 for seven.
