Lydia Ko has undergone another offseason change, with the former world number one deleting her Twitter account.

The surprising move follows Ko once again changing her caddie and coach for the 2018 LPGA Tour season, with former PGA golfer Ted Oh her new coach, and Johnny Scott her new caddie.

They replace Gary Gilchrist and Peter Godfrey respectively, with Scott set to be her 11th caddie since she turned pro in 2013.

Shortly after the announcement, it was discovered that Ko had also disappeared from Twitter.

The decision does not seem to be based on Ko receiving any abuse on the popular social platform, with most of the Twitter response to her decision being balanced.

Ko still has an active Instagram account, where she posted a positive message going into this year's campaign.

The 20-year-old failed to add to her 14 career LPGA titles in 2017 having a down year for end high standards but still finished second in three events and had 11 top tens across the year.

She held the number one spot until midway through June before slipping down to world number nine at season's end.

Ko gets her season underway at the Australian Open on Thursday morning.
