MacKinzie Kline

MacKinzie Kline (born March 30, 1992 in La Jolla, California) is an American female golfer who suffers from a heart defect known as heterotaxy syndrome as a result of being born with only one ventricle. The condition causes the blood in one's body to have little oxygen.

Kline participated in her first LPGA event in 2007 at the Ginn Tribute, and became the first player in LPGA history to ride a cart during competition. Kline, who was just 15 at the time, scored an 89 and thus will be ineligible to appear in another LPGA event until 2008.
