Scott and Williams had worked together since summer 2011, but Williams, 50, said at the start of this season that he hoped to scale back his tournament schedule and spend more time with family in New Zealand.
“After discussing this in detail with Adam it became evident that my plan was not going to fit with Adam’s requirements so we decided to end our partnership,” Williams said.
With Williams on the bag, Scott won his first career major at the 2013 Masters, ascended to No. 1 in the world this past May and developed into one of the most consistent players on any tour, finishing outside the top 25 only once this calendar year.
“Steve has been an integral part of my team in a period where I have fulfilled some of my lifetime golfing goals,” Scott said. “His dedication and professionalism have been without question, and his friendship is highly valued. Our priorities and stages of life are different now, and so we decided that this is the best time to end our partnership.”
At the start of the year, Williams said that he planned to make 2014 his last year as a full-time caddie, and that he nearly retired after the 2013 Masters – a victory, he said Wednesday, that was a “career highlight and a memory I will cherish forever.”
Williams, who also caddied for Raymond Floyd and Greg Norman, worked with Tiger Woods from 1999-2011. Together they won 13 majors, but the relationship soured in 2011 when Williams agreed to caddie for Scott while Woods was injured.
In a statement, Williams said that “if the right opportunity arose I would consider caddying on a part-time basis in the future.”
