Theodore Ernest Els is a South African professional golfer. A former World No. 1, he is nicknamed "The Big Easy" due to his physical stature along with his fluid golf swing. Among his more than 70 career victories are four major championships: the U.S. Open in 1994 at Oakmont and in 1997 at Congressional, and The Open Championship in 2002 at Muirfield and in 2012 at Royal Lytham & St Annes. He is one of six golfers to twice win both the U.S. Open and The Open Championship.

The men's major golf championships, commonly known as the major championships, and often referred to simply as the majors, are the most prestigious tournaments in golf. Historically, the national open and amateur championships of Great Britain and the United States were regarded as the majors. With the rise of professional golf in the middle of the twentieth century, the majors came to refer to the most prestigious professional tournaments.
