Eighteen-year-old Matt Fitzpatrick won the most important tournament in amatuer golf last weekend, the 2013 U.S. Amateur Championship.

And that’s not all the soon-to-be freshman at Northwestern University achieved this summer — he was the low amatuer at The Open Championship, where he finished tied for 44th. That earned him exemptions into next year’s Masters, U.S. Open and The Open Championship.

Fitzpatrick’s U.S. Amateur win was also historic — it marked the first time since 1911 that an Englishman has won the championship.

Think 18 is a pretty young age for a golfer to be making so much history? Check out these four amatuer golfers prodigies that makes Fitzpatrick look, well … old.

Lydia Ko

Age: 16
Country: New Zealand
Notable Accomplishments: Winner 2013 Ladies European Tour ISPS Handa New Zealand Women’s Open, Winner LPGA CN Canadian Women’s Open (2012 and 2013)

The discussion of golf prodigies begins with 16-year-old Lydia Ko, who is arguably the most dominant and newsworthy amateur golfers to date.

The South Korean-born New Zealand native burst onto the scene by breaking two world records by the age of 15. Ko won the ALPG’s New South Wales Open at the age of 14 to become the youngest ever to win a professional tournament. At the age of 15, Ko won the 2012 CN Canadian Women’s Open to become the youngest winner of an LPGA event, a record previously held by Lexi Thompson. She successfully defended her title at the CN Canadian Women’s Open in 2013 to win her fourth professional event, shooting 15-under to win by five shots.

A Tiger Woods-like prodigy, Ko is the top ranked amateur in the world and has held the Mark H. McCormack Medal (given to the top ranked amateur golfer in the world) for two years running. She’s still two years shy of the age limit set by the LPGA Tour, but rumor has it that her mother is seeking a waiver from the LPGA in order to join the tour on a full time basis.

Phachara Khongwatmai

Age: 14
Country: Thailand
Notable Accomplishments: Winner ASEAN PGA Tour’s Singhua Hin Open

In late July, 14-year-old Phachara Khongwatmai of Thailand won the ASEAN PGA Tour’s Singhua Hin Open breaking Lydia Ko’s youngest ever to win a professional tournament record.

Khongwatmai was born May 3, 1999, about 7 months later than Ko, who won her tournament in January of 2012.

The young teenager opened some eyes at the tournament as he finished 13-under par and won by four shots. Ryo Ishikawa had held the record before Ko, winning at the old age of 15 years and 8 months in 2007. While Khongwatmai might be a new name at the amateur level, he will be a golfer to keep an eye on in the coming years.

Guan Tianlang

Age: 14
Country: China
Notable Accomplishments: Made cut at the 2013 Masters and Zurich Classic of New Orleans, Winner Asia-Pacific Amateur Championship, Played in Volvo China Open at the age of 13

This spring, Guan Tianlang became the youngest golfer ever to make the cut at the Masters. Two weeks later, he became the youngest golfer to ever make the cut at a PGA Tour event at the Zurich Classic of New Orleans.

The 14-year-old, nicknamed “Langley Guan” for his slight build, hits the ball extremely straight and has a deft touch around the greens. The sky is the limit for him as his body matures, which should give him the distance off the tee he needs to compete against the best players in the world.

Su-Hyun Oh

Age: 17
Country: Australia
Notable Accomplishments: Winner Lake Macquarie Amateur Championship, Played in Women’s Australian Open at the age of 12

It can be said that certain eras of sports are defined by great rivalries. There was Jack Nicklaus/Arnold Palmer, Joe Frazier/Muhammad Ali and Andre Agassi/Pete Sampras. Great rivalries make sports better. So golf fans can only hope for a brewing rivalry between the No. 1-ranked women’s amatuer golfer in the world, Lydia Ko, and No. 2-ranked women’s amatuer golfer, Su-Hyun Oh, who is only one year older than Ko.

Oh’s name may not have the same recognition as Ko’s on the women’s amateur side, but her list of accomplishments may be just as impressive. As a 12-year-old, she played in the Women’s Australian Open. Earlier this year, Oh won the Lake Macquarie Amateur Championship. In 2012, she won the Port Phillip Open Amateur and Victoria Amateur Championship by nine shots. Oh also won the Srixon International Junior Girls Classic and the Australian Girls Amateur Championship.

The future looks bright for these four budding stars. As a golf fan, one can certainly be optimistic about what the professional golf circuit might look like in a few years. For now, just sit back and enjoy the ride.
