Made his major debut at the 2014 U.S. Open, but this is his first appearance at the Open Championship and his place was secured only on June 30 as one of the leading non-exempt players off the world rankings.
Two events were largely responsible for that. He captured his maiden PGA Tour success at May’s AT&T Byron Nelson in Texas, where a closing 66 enabled him to overtake Sam Burns and win by three to take the final place in the PGA Championship.
That moved him up from 137th to 59th and came three months after he was runner-up to Brooks Koepka at the Waste Management Open, Koepka chipping in for eagle at the penultimate hole to win by one.
Lee has twice lifted the Korea Open title and is also a two-time winner on the Japanese Tour, first in 2012 as a rookie professional and then again in 2015.
He also had six second-places during his time in Japan, being denied only by Hideki Matsuyama in the 2016 Japan Open.
As an amateur he won the 2009 Toytota World Junior Cup and the following year was part of the South Korean side that took gold at the Asian Games.
