Thitikul, a LPGA rookie from Thailand, is only the second player from her country to achieve the feat, after Ariya Jutanugarn did it in 2017, and Thitikul is the 16th player overall to hold the top spot in the world ranking since it began with Annika Sorenstam in 2006.
Here are five other things to know about about one of golf’s brightest superstars.
