when did mlb go to 25 man roster
Major League Baseball rosters Since 1910, when teams were first allowed to carry players under contract in excess of those allowed to participate in regular season games, the latter has been called the "active roster." With exceptions through the years for varying economic conditions (primarily during World War I, the Great Depression, post-World War II, and from 1986 to 1989 when the limit was set at 24 because of rising player salaries), the active roster has allowed up to 25 players to participate for a Major League team within specified dates, currently Opening Day to September 1. In 1968, the 25-player maximum for active rosters was made a part of the first collective bargaining agreement between the major leagues and the Major League Baseball Players Association. Since 1977, teams have been required to carry a minimum of 24 players on their active rosters as well.
Major League Baseball Rookie of the Year Award From 1947 through 1956, each BBWAA voter used discretion as to who qualified as a rookie. In 1957, the term was first defined as someone with fewer than 75 at bats or 45 innings pitched in any previous Major League season.[1] This guideline was later amended to 90 at bats, 45 innings pitched, or 45 days on a Major League roster before September 1 of the previous year.[1] The current standard of 130 at bats, 50 innings pitched or 45 days on the active roster of a Major League club (excluding time in military service or on the disabled list) before September 1 was adopted in 1971.[1][5]
