ORLANDO, Fla. (AP) -- Lydia Ko has split with instructor David Leadbetter after three years.
Leadbetter confirmed Wednesday that he is no longer working with the top-ranked Ko. The 19-old Ko hasn't commented on the decision.
''These things happen in the world of coaching, whether it's Jurgen Klinsmann with the U.S. National Soccer Team or Novak Djokovic, who just separated from his coach Boris Becker this week,'' Leadbetter said in a statement. ''This turnover is all part of the coaching business.''
Ko turned to Leadbetter when she shifted her base from New Zealand to the United States.
