Bobby Jones： Golf's Grand Slam
As a child， Bobby Jones was a golf prodigy. At age 12， he shot two rounds of 70 and， two years later， he entered his first major tournament. He lost. In fact， it wasn't until 1923， when Jones was 21， that he won his first major——the U.S. Open at Inwood Country Club in New York. He never looked back. By 1929， Jones had already won nine majors， and in 1930， he did what no other golfer has done before or since， winning all four major tournaments in a single calendar year， thus completing what became known as golf's Grand Slam. Two months later， he retired from the game at the age of 28.
