Can you please tell me who received the first million-dollar-a-year contract in major league baseball?

On Nov 19, 1979, Nolan Ryan became the first player to sign a contract for more than a million dollars per year. Richard Moss, Ryan’s agent, helped negotiate a 4-year, $4.5 million dollar contract for the future Hall of Famer, making him the highest paid player at the time.

Richard Moss was also involved in the first arbitration case that paid a player one million dollars. On February 19, 1983, he helped Fernando Valenzuela become baseball’s first million-dollar arbitration man.
