Here is the latest MLB news from the past couple of weeks:MAY 14The Major League Baseball Players Association has filed a grievance against the league, claiming that MLB did not negotiate in good faith to play as many games as possible in the shortened 2020 season, Joel Sherman of the New York Post reports. The MLBPA grievance seeks as much as $500M, which Sherman suggests is the equivalent of roughly 20 games of additional pay. Evan Drellich and Ken Rosenthal of The Athletic report that the grievance was actually filed two weeks ago, adding that the league has argued in response that 60 games was the maximum possible due to health and safety reasons. Of course, the league itself submitted proposals for larger numbers of games, although it did so with additional salary cuts which MLB knew to be a nonstarter in talks with the union.

Additionally, 83.9% of all MLB Tier 1 players, managers, coaches and other essential personnel have received at least one vaccine dose, while 77.6% of Tier 1 individuals are now considered fully vaccinated against COVID-19.
