The completion of only one game in the Readers Lincolnshire ECB Premier League put Bracebridge Heath clear at the top of the table with maximum points as Spalding suffered a second successive defeat.
Playing at Cross O’Cliff Court on a rain-interrupted day, the home side racked up 350-3.
Paul Cook made 86 off 67 balls with Brett Houston adding 98 off 58 and Nick John 137 off 119.
When John was caught off Josh Newton, Bracebridge declared – gifting Spalding seven overs.
Three wickets for Sri Lankan signing Himesh Silva and two for Houston saw the visitors slump to 72-5.
Ben Smith was then joined by Nuwan Jayasena, making a welcome return to the side, and this partnership added 97.
Smith hit 44 and Jayasena went on to make 75 and take the total to 200.
From here, the lower order dug in to pass the maximum batting points mark but Spalding just failed to hold out to the close and were dismissed for 233 in the 55th over, Silva with four wickets.
In the five other games, all first innings were completed, all going past the 200 mark, but only two went into a second innings before rain forced the teams off for good.
Louis Kimber hit 85 and Jonny Cheer added 88 for Sleaford who reached 292-8 then reduced defending champions Bourne to 44-3 before rain stopped play.
At Skegness, Chris Graser’s 71 helped the home side to 206-8 against Market Deeping before the match was abandoned.
