Baseball officials

This is an excerpt from Sports Rules Book 4th Edition PDF, The by Human Kinetics & Myles Schrag.

The umpire-in-chief (home plate umpire) is in full charge of the game. Any umpire may disqualify any player, coach, or manager for objecting to decisions or for unsporting conduct or language. The umpire's decision on any judgment call is final and may not be appealed. A manager may, however, appeal any call that they believe goes against the rules. For common officials' signals, see figure 6.2.
