Back for the first time since 2016 thanks to a joint fifth-place finish at the 2020 Arnold Palmer Invitational.
Three Open Qualifying Series spots were on offer, but the top four of Tyrrell Hatton, Marc Leishman, Sungjae Im and Bryson DeChambeau were already exempt.
Lee’s Open debut could have been as an 18-year-old in 2009 after he won the previous year's U.S. Amateur title, but he decided to turn professional instead and his first appearance did not come until 2015, thanks to his victory two weeks earlier in a four-man play-off for the PGA Tour's Greenbrier Classic.
He was already a European Tour winner by then, his success in the 2009 Johnnie Walker Classic in Australia making him the circuit’s youngest-ever champion at the time and only the second amateur to triumph.
Lee was born in South Korea, but his family emigrated to New Zealand when he was eight. Top of the world amateur rankings for 34 weeks, he leapt into the top 40 of the professional game with a joint runner-up finish behind Jordan Spieth at the 2015 Tour Championship.
He also tied for third in the 2016 Scottish Open and was runner-up to Justin Thomas at the PGA Tour’s CJ Cup in South Korea in 2019.
