[4] Murphy appeared in a supporting role in The Name of the Game, a series featuring a rotating leading cast including Tony Franciosa, Gene Barry, and Robert Stack.

Murphy played Patrick Sean Flaherty, the man who informed lottery winners of their stroke of fortune, and Colt, formerly with James Arness on NBC's short-lived crime drama, McClain's Law, portrayed the Internal Revenue Service agent, Eric Rush, who made sure the winners pay the U.S. government up front.

His character was at odds with his former wife, Gloria (Andrea Marcovicci) and his own father, Simon (Sam Wanamaker) due to his romance with executive, Shane Bradley (Yvette Mimieux).

Murphy starred in his own series Gemini Man, in which he played a secret agent who could become invisible for 15 minutes a day through the use of a special wristwatch.

Since the 1980s, when Murphy became a highly ranked tournament tennis player in California, he has continued to travel and compete on the USTA singles and doubles circuit and in celebrity events.
