Skegness 214-8, Sleaford 218-1 - Sleaford won by nine wickets.
Half centuries from Skegness’ Chris Graser and Wymanga Perera were not enough to stop Sleaford leapfrogging them in the Lincolnshire ECB Premier League as Kiwi Tim McIntosh got back amongst the runs.
McIntosh has proved to be something of a thorn in the Skegness side in recent years, and this record continued as he smacked an unbeaten century around the London Road ground.
The Sleaford opener hit 17 fours and a six in a 124-ball 127.
After topping the run charts in recent seasons, McIntosh had been having something of a lean spell this spring, but that all changed as he followed up his three wickets with three figures.
After winning the toss Skegness chose to bat first, but they lost Pradeep Chanditha early on.
That was when Graser and Perera put on 96 for the second wicket to put the seasiders in the driving seat.
Further contributions from Brendan Young and Jamie Epton gave them more reason to be optimistic, but a middle order collapse saw them slip from 165-3 to 185-7.
Skipper Sean Chamberlain steadied the ship with a quickfire 32, but the visitors fell 11 runs short of their fifth batting point.
In response, Sleaford passed the 150 mark before the seasiders made a breakthrough, Mark Chamberlain bowling Louis Kimber for 67.
McIntosh ploughed on at the rate of a run a ball to see the home side over the line with three and a half overs to spare.
The defeat saw Skegness slip to eighth place in the league table.
On Saturday they entertain bottom-of-the-table Spalding at Richmond Drive, starting at midday.
