The Major League Baseball Player’s Association has initiated a grievance proceeding against the Athletics, Marlins, Pirates, and Rays regarding those teams’ spending of revenue sharing dollars, according to a report from Marc Topkin of the Tampa Bay Times.

This general issue has been percolating for some time, even as additional concerns have arisen as to the pace of free-agent signings over the 2017-18 offseason. The MLBPA reportedly engaged with the league office over the Miami and Pittsburgh organizations’ spending earlier this year.

At the time, MLB and the teams at issue rejected the idea that there was any issue worth exploring further. Clearly, the union disagrees and also feels that two other organizations’ practices merit examination. Per Topkin, the complaint relates to spending both last year and over the present offseason.
