Changes recommended by baseball’s special committee for on-field matters, including the expansion of All-Star rosters to 34 players, including 13 pitchers, will be implemented for this season’s Mid-Summer classic scheduled to be played at Angel Stadium in Anaheim. Other new adopted rules include the use of a designated hitter every year, making a pitcher who starts on the final Sunday prior to the break ineligible to play, and allowing re-entry into a game if the last available position player at any position is injured.
