Ko switches caddies to open '23

World No 1 Lydia Ko will have a new caddie in 2023 as she reunites with David Jones, her sister and manager confirmed to Golfweek.

Ko, 25, will begin the season next week at the Aramco Saudi Ladies International with Jones, who caddied for her at the 2021 Lotte Championship. In that event, Ko posted a seven-stroke victory to halt a lengthy victory drought.

Ko's team offered no comment as to why she decided to switch caddies after having Derek Kistler on the bag last year and half of 2021.

The Kiwi star finished 2022 with the CME Group Tour Championship trophy and claimed the Rolex Player of the Year award and Vare Trophy for low scoring average.

Jones has enjoyed his share of success, caddieing for In Gee Chun when she won the 2016 Evian Championship and for Sung Hyun Park's two major titles - the 2017 US Women's Open and 2018 KPMG Women's PGA. Jones' most recent position was caddieing for Nick Taylor on the PGA Tour.
