Youngest players to make to top 20 OWGR?

[Yuck]

SJ Im is on on the verge of making it to the Top 20 OWGR at age 21. Given how the formula penalizes those with less than 40 events in a two year period, there cannot be many other players to have accomplished this. Maybe Tiger, Rory and Spieth?

I don’t know of an authoritative list, but I checked a few other names that came to mind, and couldn’t find anyone.

Ryo Ishikawa got to the top 30 at age 18.

Sergio Garica was in the Top 20 when he was 19, that is absolutely certain.

Rory made it into the Top-20 after winning the Dubai Desert Classic in February 2009, so he was 19-years-old at the time.

Tiger entered the Top 20 with a T2nd at the AT&T in 1997. So he was 21. He played 2 years at Stanford before turning pro.

Spieth only played one year of college, he entered the Top 20 with a 2nd at the T of C the first tournament of 2014. He was 20 at the time.

Rory won the Dubai Desert Classic in 2009 to move into the Top 20. He was 19. He's been #1 for 100 total weeks now, the third most ever.

Sergio won the German Masters 7 weeks after finishing runner up in the 1999 PGA. That moved him into the Top 20 at age 19.

Matteo Manaserro peaked at #25 at age 20. He was #29 as an 18 year old. Currently he is #1481 at age 26.

Ryo Ishikawa peaked at #29 as an 18 year old as well. That was 2009 when he led the Japan Tour Order of Merit with 4 wins. At age 28 he's now #96.
