WEST PALM BEACH, Fla. -- Frank Stranahan, the premier amateur of his era who contended for majors and was the first notable player to make fitness a regimen in golf, has died. He was 90. Stranahan, who died Sunday in Hospice of Palm Beach County, was regarded as the best amateur since Bobby Jones. Quattlebaum Funeral Home, which did not disclose his cause of death, said a memorial service was planned July 2. The son of a wealthy industrialist family in Ohio -- his father was the founder of Champion Spark Plug -- Stranahan combined a life of privilege with his devotion to golf to win more than 50 amateur titles, including multiples wins in the British Amateur, Western Amateur and North and South Amateur. The one title that eluded him was the U.S. Amateur. He lost in the championship match to Arnold Palmer in 1954, and then turned pro. Stranahan, who packed barbells in his suitcase to work out on the road, won six times on the PGA Tour, twice as a pro. His biggest win was the 1958 Los Angeles Open.
