Background: Theodore Ernest Els (; born 17 October 1969) is a South African professional golfer. A former World No. 1, he is known as "The Big Easy" due to his imposing physical stature (he stands 6 ft 3 in (1.91 m)) along with his fluid golf swing. Among his 71 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.
Context: 1997 was a career year for Els first winning his second U.S. Open (once again over Colin Montgomerie) this time at Congressional Country Club, making him the first foreign player since Alex Smith (1906, 1910) to win the U.S. Open twice. He defended his Buick Classic title and added the Johnnie Walker Classic to his list of victories. Els nearly won the World Match Play Championship for a fourth consecutive year, but lost to Vijay Singh in the final. 1998 and 1999 continued to be successful years for Els with 4 wins on both the PGA and European tours.  2000 started in historic fashion for Els being given a special honour by the Board of Directors of the European Tour awarding him with honorary life membership of the European Tour because of his two U.S. Opens and three World Match Play titles. 2000 was the year of runners-up for Els; with three runner-up finishes in the Majors (Masters, U.S. Open and The Open Championship) and seven second-place finishes in tournaments worldwide. Els had a disappointing 2001 season, failing to win a US PGA tour event for the first time since 1994 although he ended the year with nine second-place finishes.  2002 was arguably Els's best year, which started with a win at the Heineken Classic at the Royal Melbourne Golf Club. Then went to America and outplayed World Number one Tiger Woods to lift the Genuity Championship title. The premier moment of the season was surely his Open Championship triumph in very tough conditions at Muirfield. Els overcame a four-man playoff to take home the famous Claret Jug trophy for the first time, also quieting his critics about his mental toughness. The South African also won his fourth World Match Play title, along with his third Nedbank Challenge in the last four years, dominating a world-class field and winning by 8 shots.
