when did college baseball switch to aluminum bats
College baseball Though a wood bat is legal in NCAA competition, players overwhelmingly prefer and use a metal bat. The metal bat was implemented in college baseball in 1975.[2] Use of a metal bat is somewhat controversial. Supporters of an aluminum or composite bat note that it can increase offensive performance, as the speed of a ball off a metal bat is generally faster than off a wood bat. Those against metal, and for wood, argue that a metal bat is not safe to use, and that a metal bat doesn't prepare players for the next level, as professional baseball uses a wood bat exclusively. In the 2011 season the NCAA changed the requirements for a metal bat, reducing the maximum allowed exit speed in a way that is said to produce a feeling more like a wood bat.[3] As a result, in 2011 there was a drop-off in overall "long" drives or home runs relative to past years.[4]
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]
