Tunbridge Wells had their Kent League Premier Division lead cut to 18 points, having lost by five runs at home to second-placed Hayes on Saturday.
Wicketkeeper Liam Buttery (40) top scored in Hayes’ 185 all out while James Poulsom returned 4-32 from nine overs.
In reply, Gus Freeman (37) led the way for the hosts but Vaibhav Vaidyanath and former Kent man Alex Blake, returning 3-24 and 3-40, respectively, left Tunbridge Wells’ run-chase short.
Third-placed Sandwich Town edged a rain-disrupted match at Minster by eight runs.
The multi-talented Tom Chapman (48) top scored in Sandwich’s 193 all out in the 45th over as David Masters (2-20), Harrison Masters (2-24), James Speer (2-34) and Bill Prideaux (2-42) claimed scalps.
Set a revised target of 183 from 44 overs, Rory Smith’s 3-36 did the damage despite Jaahid Ali’s well-made 78.
St Lawrence & Highland Court slipped into one of the relegation places after they were inched out by four wickets at home by Bexley.
Kent vice-captain Jack Leaning (33) guided the home team to 181 all out, with Louie James (3-42) doing well.
Fit-again Ben Mills and West Indian overseas professional Shermon Lewis then returned 2-33 and 2-37, respectively, but wicketkeeper Ben Aldred’s 35 helped Bexley to their target.
Blackheath are just ahead of St Lawrence, having been two-wicket winners at basement boys Holmesdale.
Leo Carter’s unbeaten 176 from 146 balls inspired Holmesdale’s 273 all out despite New Zealand overseas professional Angus McKenzie (3-58) impressing.
Nathan Khelawon (3-63) took wickets, only for George Wells’ 93 to help Blackheath home with seven balls to spare.
Bromley were three-wicket home winners over Lordswood.
Opener Linden Lockhart’s 67 led Lordswood’s 162 all out as Oliver Butterfill (4-21) turned the screw.
But Bromley opener Stan Greenleaf (51) followed suit, supported by Ollie Streets’ 38, to leave wickets for Australian overseas professional Will Straker (3-53) in vain.
