Lincicome turned professional in December 2004 at age 19, after finishing in 20th place at the
LPGA Final Qualifying Tournament to earn her tour card for
2005. Home-schooled, she had graduated from high school the previous spring. Her first victory was in the
2006 HSBC Women's World Match Play Championship, where she defeated
Michelle Wie in the quarterfinals,
Lorena Ochoa in the semifinals, and
Juli Inkster in the final match. She captured her second win in April
2007 at the
Ginn Open, again holding off Ochoa to capture the victory on the 72nd hole. In
2007, Lincicome earned a spot on the U.S.
Solheim Cup team for the first time. In singles play, she lost to
Laura Davies. Years earlier, as a 12-year-old, Lincicome had carried the scoring sign for Davies at the
JCPenney Classic LPGA event, leading Davies to good-naturedly refer to Lincicome as "Sign Girl." In
2009, Lincicome won the
Kraft Nabisco Championship, an LPGA
major, after making an eagle on the final hole to leap frog
Kristy McPherson, who held a one shot lead going into the final hole. In August 2014, Lincicome lost a sudden-death playoff with
Inbee Park at the
LPGA Championship. She had held a one shot lead coming to the 72nd hole, but made bogey to fall back into a playoff. Lincicome lost the playoff at the first extra hole when she could only make a bogey to Park's par. Lincicome won her second major championship in April 2015, with a victory at the
ANA Inspiration, the second time she had won this major. She moved into a tie for the lead after eagling the 72nd hole in regulation play, just as she had done when winning the title in 2009. Lincicome prevailed in a sudden-death playoff over fellow American
Stacy Lewis, winning with a par on the third extra hole. In 2018, Lincicome was granted a sponsor's exemption into the
Barbasol Championship on the
PGA Tour. This made her the fifth woman to play in a PGA Tour sanctioned event, the first since
Michelle Wie in 2008. Lincicome missed the cut by 9 shots, scoring 78 (+6) and 71 (−1), her second round making her the second woman to break par on a PGA Tour event. Lincicome retired following the 2024 season. ==Professional wins (8)==
