The Official Professional Baseball Rules Book governs all aspects of the game of Major League Baseball beyond what happens on the field of play. There are a number of sources for these rules, but they all ultimately are sanctioned by the Office of the Commissioner of Baseball. Examples of these rules are the Rule 5 draft (so-named for the applicable section of the rule book) and the injured list. Other examples include:
- the 5/10 Rule whereby players who have been with a club for 5 consecutive years and have been a major league player for 10 years cannot be traded without their consent.
- the roster list rules (active and expanded rosters) which also determines who is eligible to play for a team in the playoffs and World Series
- tie-breaking rules for deciding which teams go to the playoffs
- implementing/enforcing the expanded playing rules issued to umpires which goes into much greater detail than the official baseball rules of play. These rules are described in the Umpire's Manual.
