Why Lydia Ko's husband is now her caddie

Lydia Ko has her husband, Jun Chung, on the bag as her caddie at this week's LPGA LOTTE Championship in Hawaii. Jun did a great job when she finished T-7 at the Amundi Evian Championship, so he gets another chance this week. Ko met Chung in Hawaii when she won this event on the LPGA, so this is a special place for her.
