Teen sensation Lydia Ko's longtime coach Guy Wilson said Monday that the New Zea­lander had split with him after 11 years, leaving him "incredibly disappointed."

Wilson, who has coached the world No.4 since she was just five, confirmed he had been sacked by Ko, who signed with management giant IMG this month after turning pro in October.

The South Korean-born Ko won her first event as a professional in Taiwan this month after a stellar amateur career, which included becoming the youngest player to win a pro tournament, at just 14.
