Snead, who at 61 years, eight months and nine days was the third-oldest winner on the Senior Tour, cited exhaustion for his withdrawal. Snead last won on the elder circuit at the 1995 Senior Players Championship and Sunday he established a new record for most time between Senior Tour victories for a player -- six years, 11 months and seven days.
The alternate who will take Snead's place is Rick Talt of Laguna Beach, California, who competed in sectional qualifying on June 17 in San Diego. Talt shot 71 at Country Club of Rancho Bernardo.
The U.S. Senior Open kicks off Thursday at Caves Valley Golf Club in Baltimore, Maryland.
