Chris Paisley said his wife "doesn't know that much about golf" but "never put a foot wrong" on her caddying debut after he claimed a first EuropeanTour title at the South African Open.
Paisley's other half, Keri, carried her husband's bag at Glendower Golf Club this week in the absence of his regular caddie, who was on holiday.
Englishman Paisley was full of praise for his rookie caddie after holding his nerve with a superb blemish-free six-under final round of 66 to be crowned champion by three shots on Sunday.
"She never put a foot wrong. It's the first time she has ever caddied and I just can't thank her enough," said the 31-year-old.
"My regular caddie is getting some stick but I just can't say enough about how good of a job she has done this week and just in life in general.
"She doesn't know that much about golf but she knows me really well and she knows when I'm going a little quicker than I usually do or getting a bit tight.
"Coming up the last fairway with her next to me was just incredible."
Asked how he would celebrate his maiden European Tour success, Paisley replied: "I'm gonna get mortal [drunk]."
