Lee was able to maintain a one-stroke lead as he earned his card to the 2013 PGA Tour.
Dong-hwan Lee hit a final-round 5-under 67 total to take home the medal at the PGA Tour Q-School on Monday.
Lee finished with a one-stroke lead over Ross Fisher and Steve LeBrun at 25-under overall to take home the honors.
A total of 26 golfers earned their PGA Tour cards for the 2013 season. Perhaps most notably, Edward Loar did not make the cut despite starting the final round of play just two shots out of the lead. Loar shot 6-over on the day and fell far enough to miss the cut by two shots. He finished the day's action with a double-bogey.
Other notable entrants to the big stage were Erik Compton, a golfer who has had two heart transplants, who finished in seventh place at 22-under. Patrick Reed qualified for the PGA Tour as well, marking it the sixth time he has qualified for the tour based off a Monday result.
