Ko remains number one after LPGA discovers computer 'bug'

Updated: 

Lydia Ko remains top of the women's world golf rankings after the LPGA reinstated her following a computer error meant Ariya Jutanugarn was incorrectly promoted to the summit.

Jutanugarn, of Thailand, was announced as the new number one following the conclusion of the ShopRite LPGA Classic on Sunday which neither she nor Ko participated in.

But following reconsideration, the LPGA announced on Monday that a mistake had been made with the projection tool, meaning Ko retains her place.

"Last week, we issued some projections which showed Ariya Jutanugarn taking over the No. 1 spot in the Rolex Women's World Golf Rankings based on player finishes at the LPGA's 2017 ShopRite LPGA Classic which concluded yesterday," the Technical Provider of the Women's World Golf Rankings said in a statement published on the LPGA's Twitter account.

"However, when official rankings were run this morning (Monday), we discovered a bug in the projection tool.

"We are working to correct the problem within the projection tool and we apologise for the error in last week's projections."
