Three rounds under par and reducing her handicap from 31 to 26 caught the eye of the voting panel.
Staples’ feat also helped her to win her club’s Millner Coasters competition during the Ladies’ Autumn Meeting.
Staples, who returned home yesterday following a holiday, said: ‘I’m shocked.
I had no idea.
I played well over the week and I think my success has come about since giving up work last January.
Having more time to play has obviously helped me – I can play more and concentrate harder with time on my hands.
‘My handicap had been going up and up.
I was down to 24 at one stage and I’m hoping to get back down there again.
Winning was a nice feeling!’ Other notable performances during September included Sue Evans of Les Mielles, who reduced her handicap to eight.
Starting the year on 13, she recorded excellent scores in April and August.
Continuing her form last month, she won her club’s Monthly Medal competition for the second consecutive month to reduce her handicap by five strokes overall.
La Moye CG’s Geoff Ramskill won the Channel Islands Seniors’ championship for the second time, while Christy McLaughlin, of the Royal Jersey, returned scores of 70 and 67 for a three-under-par total to win the JW Messervy Open Trophy.
Justin Dawes, of La Moye, won week eight of the Tuesday Evening League with 45 Stableford points, reducing his handicap to ten, and Les Mielles’ Margaret Vautier was overall Bronze Division winner at St Clement’s Open – a fine performance from a 70-year-old who has reduced her handicap by four shots to 29.
Royal Jersey’s Gavin O’Neill had a good September, winning the Club Championship after rounds of 67 and 71, two under par, while also shooting a four-under-par 64.
La Moye member Colin Amos won his Club’s Pallot Trophy with 42 Stableford points off his handicap of 20, and Les Mielles’ Betty Le Luan, another senior golfer, reduced her handicap to 26 after winning the St Clement’s Open overall.
