The discovery of a computer error prompted the LPGA to announce that Lydia Ko, not Ariya Jutanugarn, remains top of the world rankings.

New Zealand's Lydia Ko reached the top of the women's world golf rankings following a reinstatement handed to her by the LPGA after a computer error incorrectly promoted Ariya Jutanugarn to the summit.

Jutanugarn, of Thailand, was ranked as number one after the June 4 ShopRite LPGA Classic - despite the fact that neither she, nor Ko, participated.

After consideration, the LPGA announced Monday that an error had been made with its projection analytics tool, which meant Ko retained her spot atop the leaderboards.

The technical provider of the women's world golf rankings says the following in a statement posted on the LPGA's Twitter account: "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. 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."
