.....does best athlete dominate.....NOReally US Mens don’t dominate golf and the PGA tour. Are you sure about that? We have 6 out of 10 (60%) in the top 10 ranking and have 20 in the top 50 (40%). If that isn’t dominant I don’t know what is.
As for the women, we can have only 3 in the top 10 and a meager 9 in the top 50. Where as South Korea (smaller country) has 4 in the top 10 (40%) and 22 in top 50 (44%).
USA Mens numbers reflects South Korean women and both dominate their tours.
