Thompson has been making headlines since she qualified for the 2007 U.S. Women’s Open at Pine Needles at age 12. At the time, she was the youngest qualifier in championship history, but she was surpassed in 2014 by Lucy Li. At The Olympic Club in 2021, she narrowly captured her first U.S. Women's Open title, but came up one stroke short of the playoff after struggling over the final eight holes. Her decorated amateur career included winning the 2008 U.S. Girls’ Junior at age 13 and representing the USA in the 2010 Curtis Cup Match. She also represented her country in the 2008 Junior Ryder Cup and 2008 Junior Solheim Cup. She turned pro after the 2010 Curtis Cup at age 15 and registered her first victory a year later in the Navistar LPGA Classic. Her lone major triumph to date is the 2014 Kraft Nabisco Championship (now Chevron Championship). Besides her 2021 finish, Thompson shared runner-up honors in the 2019 U.S. Women's Open at the Country Club of Charleston. She has represented the United States on five Solheim Cup Teams. The native of Coral Springs, Fla., has two older brothers, Nicholas and Curtis, who are both professional golfers. Nicholas was a member of the victorious 2005 USA Walker Cup Team.
