Wirksworth & Middleton fell to defeat at Brailsford on Saturday despite two of their batsmen making centuries.
After two fairly cheap wickets Aafan Janjua made 105 and Ant Woolley 138 to help W&M to 277-4 from 43 overs at which point Woolley declared, giving Brailsford 49 overs in reply.
Led by captain Matthew Dowling’s chanceless 161 not out, the home side won using all but three balls of the extra overs.
Results elsewhere see W&M retain second place in the table with two home games remaining.
On Sunday, a weakened first XI then lost the Boolers Bayley Cup Final to Mickleover firsts by 150 runs at Ockbrook.
Stephen Lowe took 4-24, Max Marshall and Harry Wanford two wickets each and Sinethemba Mjekula one.
At 113-5 and then 155-7 Mickleover might well have had to settle for a significantly smaller total.
An eighth wicket partnership of 64, however, seemed to deflate W&M as Freddie Matthews completed a fine half-century from the last ball of the innings.
After tea W&M lost a wicket in the first over, two more in the fourth over and, at 25-5 after ten, there was no way back.
Captain for the day, Jack Allen, with 27 and Jack Ritchie, 36, restored a little pride but the last three wickets fell for two runs with just 25 overs of the 45 completed.
The second XI lost by three wickets to Marehay thirds.
Marehay, second to bottom at the start of play, won it with just two balls to spare – a result which leaves W&M with relegation worries of their own.
Batting first the seconds made 151-5, Tom Boylan making 35 and Peter Ashurst 54 not out.
In reply Marehay were 64-2 but then lost four wickets to leave them on 117-6 with six overs to go.
Andy Bromley top-scored with 40 as Liam Duffy, James Brierley and Neil Doxey had all bowled tightly – not helped by several dropped catches.
The game changed when Marehay’s Joe Burke made a rapid unbeaten 27 not out (including 16 from one late over) to just about secure the win. Duffy finished with 3-27 and Brierley 3-42.
The under-strength third XI lost to Butterley by ten wickets having scored 96, which the opposition knocked off in just 13 overs.
