Some amazing kids have been been in the news recently. Here are two who have made big achievements in the sports world.

Lydia Ko recently won the Canadian Women’s Open golf tournament. It’s a tournament for female golfers–adult golfers. Ko, however, is just 15 years old.

Ko lives in Auckland, New Zealand (where she has lived since she moved from South Korea when she was six years old). Last month she travelled to British Columbia, where she faced professional golfers at the Canadian Women’s Open.
