Here's another great reason to love Lydia Ko - her decision to dump coach Guy Wilson has given us a sporting Christmas present.

Lydia Ko's decision to part ways with coach Guy Wilson after turning professional has been under consideration for at least 10 months.

Editorial: Wilson had every right to feel "incredibly disappointed". He had achieved amazing things with Ko. But the break was, indeed, probably inevitable.

Lydia Ko says her arrangement with the coach who oversaw her rise from a five-year-old into a world-class golfer could not last, now she was living in the US.

The Herald on Sunday sports team give their views on the best and worst.

She's making her mark as one of the best female golfers in the world, but Lydia Ko will be back at school next year.

If Lydia Ko and Tiger Woods meet, it might be the American who seeks out the Kiwi's autograph because on a purely age-result comparison Ko is clearly ahead.

With a shrug of the shoulders and the words "Okay, I'll do it", teenage golfing phenomenon Lydia Ko announced she would be joining the ranks of women's professional golf.

Lydia Ko has never been to a friend's birthday party. That's part of the sacrifice and the secret of her success.
