Lydia Ko is making things tough on the course for her fellow LPGA Tour pros, but she's making things easy for those keeping track of golf's all-time records. If you're trying to figure out who the youngest golfer to ever do something is, odds are it's Ko. Here's a (growing) list of milestones the 18-year-old phenom already holds:
-- Youngest golfer to be ranked No. 1 in the world.
-- Youngest golfer to win a major championship (Sorry, Young Tom Morris).
-- Youngest golfer to win player of the year on a major tour.
-- Youngest golfer to win the LPGA's Road to the CME Globe. (She's claimed the $1 million bonus twice already)
