FOUR LPGA Tour wins and an Olympic silver medal simply isn’t enough for women’s world No.1 Lydia Ko, who has sensationally ended her working relationship with caddie Jason Hamilton.

Hamilton has been on the bag since the end of Ko’s 2014 season and helped the 19-year-old amass two Major victories and looped for 10 of her 14 LPA Tour titles.

Yet after three weeks of relatively poor form the New Zealander has told Hamilton her golf gamed needed “a different set of eyes”.

“These things happen, it’s part of the game,” Hamilton told Golf Channel.

“All Lydia told me was she wanted a different set of eyes out there,” Hamilton said to Golfweek regarding his firing. “Nothing surprises me anymore after 26 years, so I’ll be back at it in Kuala Lumpur trying to help someone else chase their dream.”

Ko has totalled $3,160,944 during her 2016 season, but her run of bad results started at the Evian Championship in September where a 2-over par total left her in a disappointing share of 43rd, before she went on to tie for 20th at the Fubon LPGA Taiwan Championship and share 51st at the LPGA KEB HanaBank Championship with a 3-over par total.

Before Ko hired Hamilton, the New Zealand star went through seven caddies during her rookie season, including her father and longtime PGA Tour looper Mike “Fluff” Cowan.
