Northamptonshire registered their first win in this season's Yorkshire Bank 40 competition with a 42-run triumph over Worcestershire at New Road.
The Steelbacks were indebted to a rapid half-century from Steven Crook as they posted a total of 219-6, with the Pears falling well short in reply at 177.
The home side paid the price for an error-strewn display in the field, dropping four chances. Crook himself was put down when he had just 10 to his name.
He made Worcestershire pay by making 61 from 42 deliveries, including hitting seven fours and two sixes. His efforts helped Northamptonshire score 61 from the last five overs of their innings.
Openers David Sales (24) and Rob Newton (37) both made useful contributions at the top of the order while Alex Wakely contributed 39 before he was bowled by Jack Shantry.
Moeen Ali was the pick of the home attack with 3-40, though he was only able to concentrate eight runs with the bat before becoming the first Worcestershire wicket to fall in their reply.
David Willey (3-28) broke through at the top order and Matthew Spriegel took wickets in successive overs before finishing with 3-29.
Thilan Samaraweera gave his side hope in stands of 53 with Daryl Mitchell (29) and 58 with Gareth Andrew (21), but it was never easy to get the ball away on a sluggish surface.
The Sri Lankan hit nine fours to make 78 from 81 deliveries but once he fell to Andrew Hall to leave the score at 156-5, Northamptonshire were in the driving seat.
