Lydia Ko won 14 LPGA tournaments including two major championships before turning 20. Tiger Woods won none on the PGA Tour at the same age. So we can start (and probably end) there.

The point is not to highlight that Woods also did not play in any PGA Tour events as a teenage pro (he did not turn pro until he was 20). The point is to show how absurd Ko's career has been up to this point. She has built one of the great teenage golf resumes ever, and she hasn't even played 100 events yet.

Ko turned 20 on Monday after hiring the 10th caddie of her career on Sunday. Peter Godfrey was voted Caddie of the Year in 2017, and he will now be on Ko's bag.

With her previous nine loopers, Ko had 57 top 10s in 97 starts on the LPGA Tour to go with just two missed cuts. She turned pro at the age of 16 and caused the LPGA Tour to waive its age limit of 18. She also accomplished the following before her 20th birthday.

  • Youngest winner in LPGA history at the CN Canadian Women's Open (15 years old).
  • Youngest player, male or female, to reach No. 1 in the world (by almost four years).
  • Youngest major winner in LPGA Tour history (by six months).
  • Youngest female ever to win two major championships (18 years old).
  • Second-youngest golfer (male or female) with two major wins behind Young Tom Morris (1869).
  • Youngest to earn $1 million (and $2 million and $3 million and $4 million and $5 million and $6 million and $7 million) in LPGA Tour history.

The Tiger comparisons for Ko are not absurd. She's as close as we have in golf today in terms of career trajectory to Big Cat. Of course, even if she wins her next three events, she will still be 11 wins shy of what Tiger did in his first 100 PGA Tour events.

He also did that at an older age, though. Ko has been grinding since she was barely into her teens which means her pace of winning and collecting majors should pick up as she enters the next decade.

Of course, there are innumerable factors that could play into why Ko wouldn't keep up the startling pace she has set thus far, and they include the variety of changes she has made with her coach, caddie and equipment.

No matter what happens in the future, though, what Ko has already accomplished has been preposterous. Any time your name is next to Young Tom Morris' in golf history, that's a good thing. Hopefully she will sustain the pace long into the future as she shoots to become the most decorated golfer in LPGA Tour history (modern era records of 72 LPGA Tour wins and 10 majors are both held by Annika Sorenstam).
