At just 17 years old, Lydia Ko could become the youngest No. 1-ranked player in the history of the game on Sunday.
If Lydia Ko wins this week's Kingsmill Championship in Virginia, Ko would overtake In-Bee Park to take the top spot in the Rolex Rankings.
Ko, who is currently ranked third in the world behind Park and Stacy Lewis, won the Swinging Skirts LPGA Classic in late April for her third career LPGA win and first since turning pro.
Lewis can become No. 1 in the world if Ko doesn't win and finishes solo second or wins herself. It would be Lewis' 10th LPGA win and second in a row after taking the North Texas Shootout by six shots.
Park can block out both from ending her 57-week reign as she is one of eight top-10 players in the field this week.
