Derbyshire bowler Steffan Jones says their bowling display cost them a chance of victory in Tuesday's CB40 draw with the Netherlands.
Jones hit 11 off 10 balls as his side scored eight off the final over to help the Falcons match their hosts' total of 163-9 in a thrilling game in Deventer.
At one stage Derbyshire were 98-5 before they rallied to avoid defeat.
Jones told the club website: "They got 20 runs too many and we didn't really bowl to our plan in the powerplay."
Derbyshire lie second in their CB40 group, one point behind leaders Middlesex.
