The 1880s were the first full decade for major league Baseball. The rules were still changing almost yearly, resulting in vast differences in player performance. Pitching staffs consisted of one or two men early in the decade, leading to most pitchers ruining their arms before age 30 and few pitchers making it through the decade.
The 1880s saw the formation of the American Association as the first rival to the National League. While it became competitive, personality conflicts led to several teams deserting the AA for the NL and the talent level began slipping before it ever reached that of the NL. The two leagues participated in a World's Series starting in 1884, with the NL winning all but one. Stars of the decade included Dan Brouthers, Deacon White and John Clarkson.
The minor leagues were slowly expanding but were in a state of constant flux. Few leagues survived for more than a couple years. Still, they were already becoming the primary training ground for future major leaguers as well as a home to washed-up ex-MLBers.
Baseball was being played on a limited stage internationally. The Cuban Winter League was active for most of the decade, but that was the lone international professional circuit to have any success.
There were no formal Negro Leagues. Several all-black teams played at times, but the top black players this decade often played in the minors. Segregation was spreading in baseball but was not the rule yet. Fleet Walker and Welday Walker even played in the majors, and other possible African-Americans who did not reveal their heritage were active. In the minors, players such as Bud Fowler, George Stovey and Frank Grant were starring in integrated leagues, often in the highest tier of the minors.
