ST AUSTELL are guaranteed a top four premier division finish following Launceston's 2-1 defeat at home to Torpoint Athletic on Monday night.
The result caps what has been an excellent first season in management for St Austell player-manager Dan Nancarrow.
The Lillywhites could yet even finish in third, with Plymouth Parkway five points above them, having played a game more.
Nancarrow said: "I'm proud of all the boys after securing a top four finish. Now let's push for third. It's not been a bad first season as manager."
After a goalless first half at Pennygillam, Torpoint, 2-0 winners at Newquay on Saturday, took the lead on the hour when Liam Thornton claimed his second goal in as many games.
But Darren Edwards' men were pegged back in the 79th minute with Sam Davey equalising for the Clarets.
However, Jimmy Alexander made sure of the points for Torpoint with an 81st minute free kick.
St Blazey went down to a second straight defeat at home to Saltash United on Monday night.
The Green & Blacks, who were soundly beaten 4-0 at St Austell last Wednesday, lost 2-1 at Blaise Park.
St Blazey had led, before goals from ex-Blazey striker Danny Zalick and Gavin Coulton sealed victory for the Ashes.
In Division One West, St Dennis scored eight second half goals to finish 8-1 winners at home to bottom of the table Foxhole Stars.
A shock result looked on the cards as Stars led when goalkeeper Brett Allen could only push Ryan Wilkins' cross into his own net in Monday's Clay Country derby.
But second half goals from Ryan Hayhurst (3), Chris Brown, Lee Rickard (2), Carl Rickard and Perry Harvey ensured an emphatic victory for Saints.
However, the game was overshadowed by referee Tim Burley's decision after the final whistle to send off Carl Rickard, who had been booked earlier.
