[2] In 2006, Yang won the Korea Open, an Asian Tour event, gaining him entry into the HSBC Champions Tournament in November 2006.

The victory earned him membership of the European Tour and moved him into the top 40 of the Official World Golf Ranking.

Yang won his first title on the PGA Tour at the 2009 Honda Classic in his 46th career start in the United States.

It was also the first time that Woods had failed to win a major after holding at least a share of the lead at the end of 54 holes.

[6] In February 2011, Yang had his best run at the WGC-Accenture Match Play Championship reaching the quarter-finals before eventually succumbing to American Matt Kuchar, 2 & 1.

A poor 2014 saw Yang finish well outside the top 150 in the FedEx Cup, which limited him to the Past Champions category for 2015.

In 2021, Yang was disqualified from 103rd PGA Championship at The Ocean Course, Kiawah Island Resort, in South Carolina for signing an incorrect scorecard following the second round.

Trying to get a 'proper job', Yang fell down a flight of stairs and tore his ACL[11] while he was learning to use an excavator for a construction company.

[12] After recovering from his knee injury, he began mandatory service in the South Korean military at the age of 21.
