Duffield and Quarndon 1sts met on Saturday in a crucial game in Division One of the Derbyshire County Cricket League.
Both sides are in the upper reaches of the division, with realistic ambitions of gaining promotion to the top flight, but in the end it was Quarndon who came out on top thanks to a four-wicket victory.
James Pipe got the Duffield innings off to a blistering start after his skipper Paul Bakel had won the toss in the local derby and opted to bat first.
Former Derbyshire wicketkeeper-batsman Pipe raced to 51 off just 24 balls, hitting six fours and three sixes along the way, before he was dismissed by Michael Lidsey to end an opening stand of 68.
Fellow opener Chris Sheldon went on to be top scorer for Duffield with 73 but only Thomas Roe (14) and Luke Webb (18 not out) managed to get into double figures as Quarndon hit back strongly.
In the end, Duffield were bowled out for 199 in 47.3 overs.
Raja Sohail Haider proved to be the star performer with the ball for Quarndon, returning the excellent figures of 6-34 in 13.3 overs.
Quarndon were ultimately made to work hard for their victory by the Duffield attack, but they reached 204-6 in 50.2 overs to win by four wickets.
Opener Thomas Ansell led the way with a fine knock of 63 for Quarndon, who were in the top two at the start of play.
Ben Spendlove chipped in with 35 and another, former Derbyshire batsman - Adrian Rollins - saw his side to victory with 42 not out, ably assisted in a crucial unbeaten partnership by 20 not out from Harry Clamp.
For Duffield, Luke Webb took three wickets and Jono Clare snared two victims but there efforts were in vain as Quarndon strengthened their position in the top two with less than a month to go.
The result means fourth-placed Duffield are now 29 points behind second-placed Quarndon, but with a game in hand.
