(Reuters) - World number one Lydia Ko, who clinched the most recent of her 14 LPGA titles in July before enduring the first barren spell of her young but already stellar career, has split from her coach David Leadbetter after three years working together. Ko and Leadbetter joined forces shortly after she turned professional in late 2013, with the then 16-year-old leaving her New Zealand-based coach Guy Wilson after 11 years in tandem. "These things happen in the world of coaching," Leadbetter said on his website (www.davidleadbetter.com).
