Lydia Ko has overhauled her support staff once again in a bid to return to the top of women's golf.
Two days out from her first tournament of the 2018 LPGA Tour season, the Women's Australian Open, New Zealander Ko confirmed she had signed with a new coach and changed her caddie.
The world No.10 announced she had ended her association with American-based South African coach Gary Gilchrist and linked up with South Korean former PGA Tour professional Ted Oh.
On Ko's bag at the Kooyonga Golf Club in Adelaide this week will be Scotsman Jonny Scott, the former long-time caddie of World Golf Hall of Fame great Laura Davies.
Scott, who began working with Ko two months ago, replaces Peter Godfrey and will be the 11th caddie the Kiwi has used on the LPGA Tour.
The 20-year-old has also employed three coaches in the last 15 months, with Gilchrist having previously come on board in place of renowned US coach David Leadbetter, with whom she enjoyed considerable success.
Ko is chasing her first win in 18 months, having steadily slipped down the rankings since losing her No.1 crown last June.
Despite failing to win any of last season's 26 LPGA Tour events, her consistency still resulted in a 12th placing on the points standings.
Ko told The Advertiser newspaper in Adelaide this week that she had lost some self-belief last year.
"Confidence is a huge thing," she said.
"Talent wise it does not change week-in, week-out, it is really confidence and how positive you are.
"I took time off to regroup and rest physically and mentally. The past month I have been training back in the States and it is good to come back and play this tournament, my first for the season."
