The Kingsmill Championship tees off on Thursday. Two golfers stand a chance of being world ranked #1 at the end of the week.
American Stacy Lewis has eight top 10 finishes this year and is currently ranked second in the world rankings. If she wins the Kingsmill Championship she climbs to #1.
New Zealand's 17 year old sensation Lydia Ko is number three in the world. If she wins, she will pass Lewis and Inbee Park for #1 honors.
