Reigning champions Bourne suffered an agonising defeat in the semi-finals of the Winkworth Cup at Sleaford on Monday.
They fell just six short of their target as Bracebridge Heath’s total of 179 for six proved enough.
Bracebridge skipper Paul Cook hit 101 off 53 balls with 12 fours and three sixes and put on 53 for the fifth wicket with Gloucester rugby-playing brother Rob.
James Keywood then claimed both Cooks in two deliveries.
Bourne got off to a flying start in reply with a 59 partnership between Conrad Louth (34) and skipper Peter Morgan, who hit 38 off 16 balls.
The onslaught continued through Jack Berry and Carl Wilson and Bourne always seemed on target for a win.
But, despite the efforts of Stuart Airey (30 not out), Bourne fell just six short of their target as they finished on 173 for five.
Bracebridge were then beaten in the final just a few hours later as Woodhall Spa took the honours.
Woodhall Spa had accounted for Spalding in the opening semi-final.
Spalding had restricted their opponents to 147 for eight off their 20 overs despite a fine innings of 84 from Jonny Cheer.
Jack Barratt bowled an economical four overs for Spalding, taking four for 20 and when openers Warren Nel and Tim Norris put on 62 without loss, Spalding were in with a good chance of reaching their target.
Woodhall Spa hit back to reduce Spalding to 85 for four and a tight spell of bowling then put the total further out of reach.
Spalding were all out for 124 in the final over, with Nel top-scoring on 55.
