Three-batter minimum, roster expansion to go on as planned

Major League Baseball went ahead with its planned rules changes for this season, including the requirement a pitcher must face at least three batters or end the half-inning, unless he is hurt.

The active roster limit will increase by one to 26 from Opening Day through Aug. 31, will drop from 40 to 28 through the end of the regular season and return to 26 for the postseason.
