Martin Kaymer golfer in the world, making him only the second German (after Bernhard Langer) to be the top-ranked golfer in the world. At the time he was the second youngest to reach world number one behind Tiger Woods, soon surpassed by Rory McIlroy in March 2012, who gained the top ranking at age 22. In April, he relinquished his number one ranking after eight weeks to Westwood, who won the Indonesian Masters. After reaching the number one ranking, Kaymer decided to undergo a swing change to be able to move the ball both ways. Frustrated with his disappointing results at the
Martin Kaymer Masters, Kaymer looked to better shape a draw, a shot he thought he needed to be able to contend at Augusta. Kaymer missed the cut at the Masters for the fourth time in 2011 and later admitted that changing his swing for Augusta was a “big mistake.” The rest of 2011 was relatively inconsistent for Kaymer. In November 2011, Kaymer won his first WGC title at the WGC-HSBC Champions event in Shanghai, China. He entered the final round trailing Fredrik Jacobson by five strokes, then shot a final round 9-under 63 to take the title by three strokes from Jacobson.
