Bracebridge on the verge of winning yet another title
Should challengers Skegness take maximum points for the rest of the season, the leaders would need 44 points from their four games to ensure top place.
Aiming to peg Bracebridge back this week are Louth who visit Cross O'Cliff Court having held third place in the league since mid-July.
Jim Morgan has strengthened Louth's batting while Jonathan Darke's return has further boosted the side in all departments.
Both Morgan and Bracebridge's Paul Cook have topped 600 runs for the season but the leaders have the upper hand in attack with Aaron Keverne-Onyon's 41 wickets putting him second in the bowling table.
On paper, Skegness should have the easier game when they entertain 11th-placed Messingham but the Scunthorpe side are capable of big scores and the Skegness track could suit their batsmen.
Grimsby are the latest visitors to Woodhall Spa's Jubilee Park (see preview above), while Spa travel to Louth on Bank Holiday Monday for a re-arranged game.
Lindum skipper Matt Rutherford tops the bowling list with 48 wickets and will be aiming to become the first to reach 50 when his side play an ever-improving Sleaford at St Giles Avenue.
Sleaford are now eighth in the table and, should Market Deeping falter, Oliver Burford's side could find themselves pushing for a place in the top half of the table.
Deeping are at home to Caistor who now look doomed to relegation should the winners of either the Lincolnshire County Cricket League or the South Lincolnshire & Border League be eligible for promotion.
Nettleham host Bourne with both sides in the unaccustomed positions of ninth and 10th respectively after a good first half of the season.
