The Major League Baseball Players Association is still frustrated over playing a 60-game season in 2020. The MLBPA reportedly filed a grievance against the league seeking $500 million in damages, according to Joel Sherman of the New York Post.

The grievance argues the league did not act in good faith when negotiating the length of the regular season in 2020. When the 2020 regular season was put on hold last March, the players and league agreed that players would receive prorated salaries depending on how many games were played in 2020.

As those negotiations dragged on, the league and its owners asked players to take less money per game. The players did not budge, eventually leaving it to MLB commissioner Rob Manfred to set the number of games that would be played during the 2020 regular season. Manfred decided on 60 games, and later admitted the league and its owners never intended to play more than that.
