The collective bargaining agreement between Major League Baseball and the Major League Baseball Players Association (MLBPA) expired at 11:59 p.m. ET Wednesday without a new deal in place, leading to the first official work stoppage in more than 25 years.
At 12:01 Thursday morning, the league informed the players that it had locked them out, marking the first management lockout since the 1994–95 seasons, when a strike led to the cancellation of the World Series for the first time in 90 years.
