These eventually became accepted parts of the game, and the rules evolved to reflect the new situations. The mask, chest protector and shin guards for catchers and umpires came next. These changes date from the 19th century. Equipment has continued to evolve and new pieces and modifications have gained acceptance. However, the changes did not come quickly or without controversy.
Batting helmets are relatively new additions to the protection of baseball players.
Their effectiveness was much debated early on, although they now are accepted at every level of play. In more recent years, face protection has appeared in the form of either clear shields or wire masks. People have been slow to adopt them, except in the case of players recovering from facial injuries. The development of various chest protectors intended for use by youth players other than catchers is more controversial. In addition to protective gear, other items of equipment have been developed with the intention of minimizing risk to players.
