An update to our prior post “Baseball Tries An Old Saw: “Let’s not compete on wages….”:  On different grounds, there is a new challenge to Baseball’s antitrust exemption, brought by four of the minor league baseball clubs which lost their MLB affiliation in the recent shakeup of the minor leagues’ organization.  See the complaint here.  Antitrust expertise has long been a strong suit of the law firm representing these plaintiffs, so it appears that the complaint is a serious and well-backed endeavor.
