Alexis Noel "Lexi" Thompson (born February 10, 1995) is an American professional golfer who plays on the LPGA Tour. At age 12, she was the youngest golfer ever to qualify to play in the U.S. Women's Open. She turned professional in June 2010 at age 15. On September 18, 2011, Thompson set a then new record as the youngest-ever winner of an LPGA tournament, at age 16 years, seven months, and eight days, when she won the Navistar LPGA Classic. Three months later she became the second-youngest winner of a Ladies European Tour event, capturing the Dubai Ladies Masters by four strokes on December 17, 2011. She won her first major championship at the 2014 Kraft Nabisco Championship at the age of 19 years, 1 month and 27 days, making her the second youngest LPGA golfer to win a major (she still ranks in the top-5 youngest LPGA major winners).
