Long Sutton were edged out in a last-over thriller at the Paradise Field on Saturday.
Having been asked to bat, Sutton lost an early wicket but recovered well with a fine partnership between skipper Phil Barnes (87) and Adam Wright (44).
When Wright was dismissed, in-form Luke Lovegrove continued to push the scoring on and a late flurry of boundaries from all-rounder Rob Simpson helped Sutton to a respectable 210-8.
Grantham 2nd started well with their reply but a wicket for Barry Stanway soon pegged them back.
And when the number three was superbly stumped by Wright off the bowling of Jake Burton, Sutton were right back in it.
Grantham’s middle order continued to score runs steadily and looked as though they would cruise home.
However the reintroduction of Stanway and some tight bowling from Simpson hauled Sutton back into the game.
It was down to the last over and with Grantham needing just five runs they had to be favourites.
Burton struck with the first ball of the over to set the nerves jangling but Grantham’s tail wagged and they made it home with just one ball to spare.
Meanwhile, Boston’s lead in the South Lincolnshire & Border League Premier Division was cut after Bourne 2nd beat Lindum Ramblers while the leaders dropped a point in their victory over Belton Park.

Sumit Puri put in a man-of-the-match performance for Sleaford 2nd, hitting 63 runs and taking five wickets in his side’s win over Harrox.
The highest scoring and tightest game came at Billingborough where Woodhall Spa 2nd finished on 239-9 with new signing Daelon Campbell hitting 87.
But the home side were also in good batting form, Mitch Griffiths making 51, and Billingborough were just five runs short of their target with eight wickets down.
