McAllister looked to be falling out of the tournament as he reached the turn in level par, but a thrilling back nine of 30 saw him charge up the leaderboard and pocket £9,849 for his efforts at the Golf Club Bad Ragaz.
Torrance’s 65 saw him finish the week on five under, two shots behind eighth-placed Bill Longmuir but six ahead of Gordon Brand Jnr.
Sir Bob Charles and Gary Player continued to amaze the world of golf with their unbelievable levels of performance in Switzerland.

Charles added a 73 and a 72 to his remarkable first round to finish the week at one over par – two ahead of Player – and in a tie for 42nd place.
