Helston’s five match winning run came to an end at Roche on Saturday, when they lost by six wickets with almost four overs to spare.
Monday’s game with Hayle was washed out, as was the reverse fixture at the Towans on Spring Bank Holiday Monday. It means Helston’s hopes of finishing in second spot look over.
With just two games to go they trail Hayle by 21 points. Roche are 12 points behind in fourth. Helston’s final away game is at relegated Menheniot Looe on Saturday before finishing at home to champions elect Penzance.
Hayle host the other relegated side Stithians and then visit Troon.
At Roche Helston suffered early shocks with Ross Leathley bowled by Ryan Clark for four. Dan Jenkin and Chris Martin took the score to 29 before three wickets fell for two runs.
Jenkin was lbw to Dan Best for 15. A run later Best trapped Martin in front for eight. Then Tommy Sturgess was bowled by Clark for one and at 31 for four the visitors had problems.
Ben Rule and Steve Jenkin (24) added a useful 66 for the fifth wicket but Courtney Rowe struck twice to remove Jenkin and Josh Ninnis without a run added. Rule went on to make 63 off 120 balls with six boundaries before being run out.
Jordan Fulton got double figures in the 171 all out with two overs unused. Daniel Best, Ryan Clark, Courtney Rowe and Shaun Trudgeon all took two wickets. Adam Brenton secured the win with an unbeaten 80. Adam Trudgeon (20), Neil Trudgeon (25) and Will Skene (32) all played their part with victory coming in the 47th over.
Ross Leathley got two for 29 with one each for Steve Jenkin and Peter Boyd. All six County Division 1 games were cancelled on Monday. Penzance need just 3 points for the title from their last two games while Menheniot Looe and Stithians have been relegated over the weekend.
