TAMPA, Fla. (AP) — Major League Baseball has proposed banning player access to video during games, according to New York Yankees pitcher Zack Britton, but the union wants to allow it with protections that would prevent catchers' signs from being visible. Houston violated rules by using a camera in the outfield to steal catchers' signs during its run to the 2017 World Series title and again in 2018. MLB also is investigating whether Boston broke rules. Players' association head Tony Clark said the union is open to setting rules for player discipline for future technology rules violations.
