Chicago Cubs third baseman Kris Bryant and Philadelphia Phillies third baseman Maikel Franco have filed grievances against their teams alleging they were kept in the minor leagues unnecessarily and had their service time manipulated to delay future free agency, multiple major league sources told Yahoo Sports. Potential service-time manipulation looms as a significant issue with Major League Baseball and the MLB Players Association ramping up discussions on a new collective bargaining agreement after the current one expires Dec. 1, 2016. While neither case has yet to reach an arbitration panel, according to sources, the grievances indicate that players believe teams have not abided by the intention of service-time rules and operated in bad faith.
