The Union Association survived for only one season (1884), as did the Players' League (1890), an attempt to return to the National Association structure of a league controlled by the players themselves. Both leagues are considered major leagues by many baseball researchers because of the perceived high caliber of play and the number of star players featured. However, some researchers have disputed the major league status of the Union Association, pointing out that franchises came and went and contending that the St. Louis club, which was deliberately "stacked" by the league's president (who owned that club), was the only club that was anywhere close to major league caliber.
With the Little League® International Board of Directors formally adopting USA Baseball’s new standard for bat performance testing, Little League International fully supports this program. For more than seventy-five years, Little League has used improvements in science, engineering, and technology to take the sport of baseball to higher levels. By utilizing the most current advancements available, manufacturers can now develop bats with a wood-like performance, which is important for the long-term success of the game. Developed by a USA Baseball committee of scientific experts, Little League Baseball® has decided to adopt the new bat standard for mandated use effective January 1, 2018. All national members of USA Baseball, including Little League, are encouraged to adopt this new standard. Little League-approved bats can be used through December 31, 2017, and our current bat regulations will be in effect until then. That includes the moratorium prohibiting the use of all 2 ¼ inch barrel baseball bats constructed with composite material in the barrel, unless approved. Visit for detailed information. Little League looks forward to working with USA Baseball, and will begin educating our local leagues, and the parents of our million baseball players, preparing them for the important change coming in 2018.
