Robert Trent Jones Sr, who designed many of the world's greatest golf courses, died yesterday at his home in Fort Lauderdale. He was 93.

Jones designed some 310 golf courses in 45 US states as well as courses on every continent but Australia and Antarctica. He is responsible for 20 of the 100 greatest courses in America, according to rankings in Golf Digest.

Jones would have turned 94 on Tuesday, two days after the 100th US Open is to be decided.

He is survived by his two sons, both of whom are course architects, and four grandchildren.
