NEW YORK — Hall of Fame pitcher Tom Seaver has been diagnosed with dementia and has retired from public life.The family of the 74-year-old made the announcement Thursday through the Hall. They say Seaver will continue to work in the vineyard at his home in California.Seaver has limited his public appearances in recent years. He didn't attend the Baseball Writers' Association of America dinner in January when members of the New York Mets' 1969 World Series championship team were honored.This makes me sadder than the Trebek news in my opinion.
