Just seven points span the top four teams in Spalding and District League Division Three ahead of what promises to be a terrific title race.
Leaders Holbeach B do have a six-point lead at the summit, having battled to a 5-1 triumph over a game Donington D outfit.
Neil Harvey (O7) shone with a 30 break for the table-toppers, while Zac Rowlett (O28) won a crucial black-ball game in the second frame.
That piled the pressure on second-placed Gosberton A – but they slumped to a 5-1 home loss against Boundary C.
A 22 clearance from Carl Wand (R7) in a final frame triumph was in vain for the promotion hopefuls, as Mick Walker (O21), Josh Agger (R21), Aidan Sutton (R14) and Steve Walker (R7) all delivered for the Deepings side.
That untimely defeat allowed Donington B and Bourne SC B to close right in on them after both won 5-1.
A fine 30 break from Tony Scully (scr) helped Donington see of Gosberton C, while Bourne dispatched Consti D.
Up in Division One, Services A suffered a potentially damaging 4-2 defeat at Holbeach A. The title-chasers were undone by frame wins from Richard Lowe (O7), Jeremy Merrison (O35) and, crucially, Mark Hubbard (O14).
Moving in the opposite direction are Donington A, who propelled up to fourth following a fine 5-1 victory at Tulips A. Richard Major (R7), Nigel Brasier (scr), Jim Thompson (O7) and Sam Major (O14) were all winners for Donington.
Bren Bowman (O63) made breaks of 28 and 24, but his Tulips side have now suffered seven losses in their last nine.
At the other end of the table, Long Sutton B gave themselves some breathing space above the drop zone after knocking off Pyramid A 4-2.
Wayne Dent (O42) and Carl Parnell (O42) pocketed breaks of 30 and 27 respectively for the strugglers.
Meanwhile, Consti F’s charge towards the Division Two title continued with a 5-1 home success over club rivals Consti I. The long-term leaders are now 11 points clear of the rest, but have played more games than most of their rivals.
Whittlesey A were the big winners of the day, having trounced hosts Consti H 6-0.
A black-ball victory from Day Thewliss (scr) sealed their whitewash return.
Elsewhere, Paul Cook (scr) trousered a 24 break to help Crowland A see off Pyramid D, for whom Matt Allen (O42) notched a 22 break.
Andy Mowforth’s (O14) 20 break was the highlight of Boundary A’s 5-1 home return against Crowland B – a result that leaves the latter deep in the relegation mire.
Just below them are Whittlesey C, who crucially beat Services C 4-2.
