The lockout was due to the expiration of the CBA (Collective Bargaining Agreement) in December. Because the MLBPA (also known as the Player’s Association, or the union) and the MLB weren’t able to reach an agreement before the CBA expired, owners voted to carry out a lockout. The timing of the lockout allows owners to negotiate without being threatened with game disruptions. Although there have been few breakthroughs in talks, many hope both parties can settle on a new deal before the new season is scheduled to start on March 31, 2022.
