Boston need just 21 points from their last three games to be sure of the South Lincolnshire & Border League championship but the race for second place is still wide open with Woodhall Spa 2nd two points behind Sleaford 2nd.
Sam Elliott took his first five-wicket haul for Boston’s first team, ending with seven Moulton Harrox wickets for 19 in the leaders’ 10-wicket win.
Sumit Puri hit 76 to help Sleaford to victory over Billingborough.
Things remain tight at the bottom of the table with just three points separating Belton Park and Spalding 2nd from 11th-placed Long Sutton.
Sutton were involved in the tightest game of the day, hitting 179-7, Chris Booth with 59, then taking Spalding’s last wicket with their opponents just 17 runs short of their target, Jamie Juckes making 64.
In Division One, Freiston’s best batting performance of the season kept them in with a slim chance of claiming the second promotion place behind Market Deeping who were without a game.
Second-placed Boston 2nd piled on the runs, Michael Musson hitting an unbeaten 150 off 129 balls – the day’s only century – and Tom Poole with 96.
The final total was 342-3 and Long Sutton 2nd were then bowled out for 48, Ben Troops taking 3-10 off three overs.
Mike Stanley took his total runs for the season to 785 with an innings of 69 but could not prevent Billingborough 2nd’s four-wicket defeat by Cavaliers.
Baston took the chance to open up a 12-point lead in Division Two after second-placed Timberland went down to Claypole by three wickets.
Tim Dyer took 5-26 for Baston in their 10-wicket win over Boston 3rd.
But the best bowling came from Pinchbeck’s Andrew Beeston who, in nine overs, took five wickets for just six runs to help his side to victory over Spalding 3rd.
Heavy rain forced the abandonment of Grantham 4th’s game after the home side had made 139, Ian Robinson hitting 63 and Phil Sharp taking five wickets.
Sharp was unbeaten on 27 as Burgh & District reached 61-1 before the game was washed out.
