Isao Aoki

Isao Aoki (青木 功, Aoki Isao?, born 31 August 1942) is one of Japan's most successful golfers. He was elected to the World Golf Hall of Fame in 2004.

Aoki was born in Abiko, Chiba, Japan. He was introduced to golf while caddying at the Abiko Golf Club as a schoolboy. He turned professional in 1964. He went on to win more than fifty events on the Japan Golf Tour between 1972 and 1990, trailing only Masashi "Jumbo" Ozaki on the golfers with most Japan Golf Tour wins list. He won the Japan Golf Tour money list five times in six years: 1976, 1978, 1979, 1980, and 1981. His career earnings are 980 million yen.

In 1983, Aoki won the Hawaiian Open on the U.S. based PGA Tour and the Panasonic European Open on the European Tour. He also won the prestigious World Match Play Championship in England in 1978, which was not a European Tour event at that time, and picked up a win on the PGA Tour of Australasia.

Aoki played 165 times on the PGA Tour between 1974 and 1999, primarily from 1981 to 1990. His best finish in a major championship was a second place finish to Jack Nicklaus (by two strokes) in the 1980 U.S. Open. That finish, combined with his recent record in Japan and around the globe, meant that Aoki would finish 1980 ranked third in the unofficial McCormack's World Golf Rankings, a position he would hold at the end of 1981. After the Official World Golf Rankings debuted in 1986, he was ranked in the top-10 for several weeks in 1987.

As a senior, Aoki has played mainly in the United States on the Champions Tour, winning nine times between 1992 and 2003. He has eight senior victories outside the United States, including five victories in the Japan Senior Open where he shot his age, 65, during his most recent triumph in 2007.
