Denby’s run of successive wins came to an abrubt end when they were hammered by fellow promotion challengers Swarkestone by 173 runs.
Denby skipper Joe Greenhalgh won the toss and asked Swarkestone to bat first but despite the early loss of Ben McGonigal the innings prospered.
Opener Guthrie took full advantage of missed chances by batting throughout to hit an unbeaten 111.
Tom Hamilton hit 55 and Derbyshire pair Ross Whiteley and Tom Poynton made 36 and 24 respectively as the innings closed on a daunting 269 for 5, the only bowler to come out with any credit being Jake Sherriff who persevered for 13 overs taking 2 for 50.
Any hopes Denby had of victory were soon removed as the Swarkestone bowlers were quickly in full control.
Bruce Dilks picked up 4 for 18 as the score slumped to 37 for 6 while Whiteley finished with 5 for 24 as Denby slumped to 96 all out.
Stuart Poplar made an unbeaten 37 batting at eight but the last wicket fell with some ten overs remaining to give Swarkestone the maximum 27 points to Denby’s two points.
Denby seconds struggled to a losing draw in a reduced overs game against Aston-on-Trent.
In a match of 30 overs per side it was Denby who took the early initiative as Fraser Kirk took 2 for 24 in a fiery spell.
But despite a couple of wickets from Gary Cresswell, Aston’s batsmen were in good form and Fahim Shabbir made an impressive 62, with Mohammed Azad (28) and Fahad Shabbir (28) providing good support as Aston posted a pretty decent 175.
The experienced Shakeel Aslam was soon making inroads into the Denby innings as they slumped to 50 for 6 before youngsters Kirk (34*) and Rob Peat came together to blunt Aston’s victory push and hold out for a losing draw.
Denby thirds were caught out on a wet wicket when they travelled to Matlock.
After slumping to 10 for 3 they never really recovered and were bowled out for 112.
But Matlock slumped to 84 for 8 as the pace was taken off the ball and Denby sensed victory, but the tail batsmen held on for victory.
The fourths secured the only positive result of the day with a winning draw against Ambergate.
Paul Kay (69) and Nathan Clarke (53*) ensured Denby were in a strong position as their innings finished on 169 for 3 from 34 overs.
Ambergate were never really in the hunt as wickets fell at regular intervals.
Kay made an impact again in taking 3 for 25 and Andy Parkin picked up 3 for 34 as Ambergate fell away to 124 for 8 to give them five points to Denby’s 16.
