SANDY BARON, a standup comic best known for his recurring role as Jack Klompus, an irritating oldster on "Seinfeld," died on Sunday at the age of 64, according to the Associated Press. He suffered from emphysema. In addition to his role on "Seinfeld," Baron also made frequent television appearances on "Law and Order," "Crime Story" and "Starsky and Hutch." AL MCGWIRE, Hall of Fame basketball coach and, later, CBS sportscaster, died Friday at the age of 72. McGwire was reportedly battling leukemia, but the exact cause of death has not been disclosed. He enjoyed a brief NBA career that ended in 1955, and then made his mark on the sport as a coach and broadcaster, earning him election to the Hall of Fame in 1992. NBC broadcaster Bob Costas, who worked with McGuire and occasionally substituted for him, described him as "a genuine original who came out of a time when there were real characters in sports, not packaged images." McGwire is survived by his wife, three children, a brother and six grandchildren.
