In 2007, at just 12 years of age, Lexi Thompson became the youngest golfer to qualify for the US Women's Open. She failed to make the cut but her record stood for seven years, before Lucy Li surpassed her in 2014.
A year later, Thompson went on to win the US Girl's Junior championship and again qualified for the US Women's Open -- with her brother, PGA TOUR player Nicholas Thompson, there to help. She again failed to make the cut, but it would be a case of third time lucky ...
With her dad as caddy in 2009, Thompson qualified for her third successive US Women's Open, this time making the cut and finishing an impressive tied 34th.
For the first half of 2010, Thompson continued competing as an amateur and her results only got better. At the Women's Australian Open, she finished T16, before going on to play a crucial part in Team USA's Curtis Cup victory.
In June, Thompson announced she would be turning professional, just in time for her fourth consecutive US Women's Open. Thompson recorded her best ever finish at the tournament, tying for 10th and scooping her first professional paycheck -- a cool $72,131.
In 2010, Thompson recorded her best Tour finish, tying second at the Evian Masters and finishing just one shot behind eventual winner Jiyai Shin. Thompson received $242,711 for her efforts ... not a bad pay day for a 15-year-old!
Thompson claimed her first ever LPGA Tour victory at the 2011 Navistar Classic. At the age of just 16, she became the youngest ever winner on the LPGA Tour. However, Lydia Ko would surpass her record 11 months later.
After winning the Navistar Classic, Thompson successfully petitioned for a waiver which saw the LPGA allow her to become a Tour member, despite not yet being 18 years old. In 2013, Thompson won her second Tour event, the 2013 Sime Darby, and the third, Lorena Ochoa Invitational, followed soon after.
Thompson won her first major a year later, famously jumping into the lake with caddie Benji Thompson (no relation) after victory in the 2014 Kraft Nabisco Championship.
Still only 22, Thompson has gone on to win nine LGPA Tour titles in total, the latest coming at the 2017 Indy Women in Tech Championship.
