Bourne’s reputation for tight finishes this season continued at Abbey Lawn where close neighbours Market Deeping were the visitors.
The home side won the toss and elected to bat, Jordan Temple’s 74 helping the score to 106 for four.
From here, Steve Crossley joined Pete Morgan to score his first century since moving to the club, hitting a flawless 102 and sharing a unbeaten stand of 170, Morgan making 67 as Bourne racked up 276 for four.
Deeping’s chase saw them reach 107 for three, Josh Smith contributing 46.
James Hook’s 54 helped the visitors to 205 for six but when two more wickets fell on 213, Bourne were favourites to win.
But Lee Peacock had other ideas as the Deeping veteran launched an attack on the bowlers that brought him 51 runs off 22 balls with three fours and five sixes.
When Peacock was bowled, just eight runs were needed and the final pair took their side to victory with just one ball to spare.
