The Major League Baseball Players Association issued a statement on Tuesday ripping teams for their supposed concerted effort to drive down the price of free agents, and the league returned fire shortly thereafter.

After MLBPA executive director Tony Clark accused MLB teams of engaging in a “race to the bottom,” the league responded that clubs are only concerned with winning and should not be blamed for agents who are advising their clients to hold out for contracts that are above market value.

A lot of factors have led to players like Yu Darvish, Jake Arrieta and J.D. Martinez remaining unsigned with pitchers and catchers set to report to spring training next week.
