|Derbyshire won by seven wickets|
Opener Billy Godleman hit 109 not out as Derbyshire timed their run-chase perfectly to beat Northants by seven wickets in the One-Day Cup.
Josh Cobb made 104 for the visitors, but teenage leg-spinner Matt Critchley took 4-48 as they were all out for 231.
Godleman's stand of 104 with Wayne Madsen (52) put Derbyshire on course for their target, but Northants were unhappy at an enforced ball change.
David Willey took 2-36, but the home side reached 232-3 with 10 balls left.
Northants were well placed at 143-2 in the 31st over of their innings, but Ben Duckett fell to Mark Footitt (2-54) and only managed to add 88 more runs, with Cobb and last man Azharullah dismissed by Ben Cotton (2-50) with the final two balls of their innings.
Godleman and Wes Durston (32) began the reply with a stand of 68 and despite the loss of Madsen and Critchley in quick succession after they reached 172-1, Godleman progressed to his maiden one-day hundred off 151 balls and won the game with his seventh boundary.
Derbyshire were without New Zealand batsman Hamish Rutherford who will also miss the final two games of his stint for the club because of thumb and abdominal injuries.
Derbyshire batsman Billy Godleman:
"It was a really good all-round team performance and we took the game deep and managed to get over the line when chasing which has been difficult previously this season.
"It looked like the new ball was going to be the best time to score, and I knew that the middle overs were going to be difficult, so it was just about making sure I kept my composure and rotated the strike."
Northants head coach David Ripley:
"I haven't spoken to the umpires but they felt the ball had changed unnaturally, but our view was it was reversing because we'd bowled a lot of seam at that end and spin at the other.
"The umpires felt there was something not quite right but there's certainly no allegation of ball tampering because we didn't incur any penalty runs, it was just they felt the ball had changed and they needed to change it.
"Anything that happened we felt happened naturally and maybe accidentally with throwing the ball in."
