In baseball history, which organization represents players and gained significant influence under Marvin Miller?

• A. Baseball Players Association
• B. Major League Baseball Players Association (MLBPA)
• C. NFL Players Union
• D. American Players Guild

Answer: (B)

Marvin Miller’s impact came from building the players’ union into a powerful bargaining voice for baseball players. He led the Major League Baseball Players Association, turning it into a highly organized, influential group that fought for and secured collective bargaining rights, better salaries, and improved contract terms. This shift gave players real leverage in negotiations with team owners and helped reshape the economics of the game.

The other options don’t fit the baseball context: they refer to unions in football or to groups that aren’t the recognized MLB players’ union. So the organization that gained significant influence under Miller is the Major League Baseball Players Association.
