After a string of poor results, Lydia Ko has decided to part ways with her long-time caddie in an attempt to get her season back on track.

Ko's coach David Leadbetter told Radio Sport this morning the Kiwi golfer and her Australian caddie Jason Hamilton ended their partnership on the green last week.
"I think that's been on her mind a little bit. The reasons are a little uncertain at the moment. They felt they weren't getting on together, it wasn't acrimonious in any way," he said.
It comes after poor performances in her last three outings - capped off with the world number one finishing in a tie for 51st at the EB HanaBank Championship in South Korea last weekend.
The two have had great success since Ko hired Hamilton at the end of 2014 with the pair combining for 10 of Ko's 14 LPGA wins, including both her major titles.
But Hamilton told Golfweek he took the decision in his stride.
"All Lydia told me was she wanted a different set of eyes out there," he said.
"Nothing surprises me anymore after 26 years."
Leadbetter says it's now about finding the right caddie to work with the successful 19-year-old.
"I'm sure next year, whoever it may be, she'll have a good caddie. Every man and his dog wants to caddie for Lydia.
"She's very easy to work with. She's not overly demanding and she's a pleasure to be around."
Ko competes at the Sime Darby Malaysia in Kuala Lumpur next week.
