Fourteen-year-old Lydia Ko has become the youngest person — male or female — ever to win a professional golf tournament.
The teen won the New South Wales Open golf tournament on Jan. 29.
Ko was born in South Korea but moved with her family to New Zealand in 2003. She is the world’s top amateur golfer.
Ko won the tournament by four strokes. That means that the person who came in second took four more shots than Ko did, to complete 18 holes of golf. (In golf, unlike most sports, the winner is the person with the lowest score.)
