Pinchbeck got back to winning ways on Saturday with Sam Smith’s 70 not out the telling contribution.
Put into bat, Grantham’s openers played positively and chalked up 44 before Pinchbeck hit back with quick wickets.
Skipper Langford and Andy Beeston both struck before Steve Robinson made an immediate impact to remove the dangerous Shaw (33).
Pinchbeck reinforced that damage as Beeston (2-29) claimed another victim to complete a great spell and Langford (3-40) returned to add a further brace, reducing the total to 98-6.
But Grantham’s lower order showed some steel and, aided by some pretty sloppy fielding from the hosts along the way, they were able to bat through their overs and post a creditable final total of 145-7.
Pinchbeck’s reply started steadily but in the face of tidy bowling from the new ball pair both openers were sent back with the score on 43.
But Smith once again anchored the hosts’ innings and followed up his unbeaten century last time out with a well measured half century to see the home side over the line for the loss of only one further wicket.
Having taken time to settle down Smith began to play his strokes and dominate the Grantham bowlers as victory was achieved with 11 overs to spare.
