Si-Woo Kim

At 21 became the youngest-ever winner of The Players in 2017, beating Ian Poulter and Louis Oosthuizen by three when ranked 75th in the world. 

It was his first top-20 finish of the year, yet Kim had already secured an Open debut for himself at Royal Birkdale by making it through the 2016 FedEx Cup play-off series all the way to the concluding Tour Championship. 

Sawgrass was his second PGA Tour victory – in 2016 he finished five clear of Luke Donald at the Wyndham Championship after posting a second round 60. 
In 2012 he was the youngest player to survive the PGA Tour qualifying school, but being only 17 at the time he could not join the circuit until his next birthday. 

In his first eight events he did not make a single halfway cut, but two years later he was the second youngest winner – behind Jason Day – on the Web.com Tour and on the same day that Henrik Stenson was winning the Claret Jug at Royal Troon in 2016 he finished runner-up to Aaron Baddeley at the Barbasol Championship. 

Made his Presidents Cup debut in 2017 and last season lost a play-off for the RBC Heritage to Satoshi Kodaira.
