Nutbrook hosted fellow promotion challengers Langley Mill on Saturday but were beaten by 78 runs.
Home skipper Steve Sanderson won the toss and put the Millers into bat first but two quick wickets fell, Paul Bailey and Jamie Salmons both out to catches off the bowling of Danny Brooks.
A big third wicket stand between Lewis Pinder and Sajendra Thimal put the Millers back in control and they were 104-3 after 23 overs.
Sanderson turned to spinners Harry Duckles and Rich Henshaw to halt the progress but it was paceman Ruan Markram who took the next wicket, getting Pinder out lbw.
Langley Mill then lost quick wickets and were 183-9 in the 41st over, but some forceful batting by the lower order gave them a final score of 211 all out, Henshaw taking 4-36, Brooks 2-39, Duckles 2-70 and Markram 1-31.
Nutbrook’s reply got off to the worst possible start as they lost their first three wickets for just 16 runs and in only six overs, Chris Palfreyman, Michael Chambers and Markram all back in the pavilion.
The batsmen never got to grips with bowlers Jack Scott and Jay Holmes and none got out of the 20s, the end coming in the 40th over.
Henshaw top scored with 25, Tom Bentley hit 23 and Sanderson also 23 as Nutbrook dropped to third in the table.
Nutbrook seconds were away at a very windy Pilsley where skipper Lewis Haywood won the toss and asked the hosts to bat.
This turned out to be a good move as Chris Goring tore into the Pilsley batting, helped by Tom North and Mark Witham as Pilsley were all out for 87 in 21.4 overs.
Witham and Ben Eaton got Nutbrook off to a good start before Witham was out for 28 but Eaton and Jonny Taylor carried on to reach the target inside 26 overs, Taylor not out on 48 and Eaton 23.
Nutbrook thirds visited Stanton-by-Dale and were put into bat first.
They lost quick wickets but Joe Newnham and Rob Gilbert steadied the ship until Gilbert was run out.
Good batting by the younger players and a huge six from 15-year-old Victor Hartshorne helped Nutbrook to 112 all out.
In reply, two early wickets were lost by Stanton but they went on to win despite Richard Edwards’ 3-30 and James Taylor, Joe Taylor and Hartshorne also claiming wickets.
