Hahn, who turned pro earlier this year after playing NCAA golf at Vanderbilt, shot rounds of 71-72-70 to finish at 3-under 213. That was good for a one-stroke win over runner-up Chirapat Jao-Jivanil. A front-nine 33 (that included an eagle on the second hole) in the final round propelled Hahn to the victory.
It had to be a particularly sweet victory for Hahn - even more than for "just" getting No. 1 - because it was a hometown victory. Hahn is from Las Vegas and played at Green Valley High School there.
Hahn posted three Top 10 finishes in her recently completed senior season at Vanderbilt. Her career highlights before this included winning the individual championship at the 2014 NCAA East Regional (leading Vanderbilt to the team championship), becoming at that time only the second Vandy female golfer to win an NCAA tournament. She also was co-medalist at the 2015 U.S. Women's Amateur.
