Louisville Colonels

After spending several years as a well-known semi-pro team, the Eclipse joined the newly made American Association in 1882. The Eclipse's backer, local distiller J. H. Pank, was named vice-president of the AA, and the team was to be run by a consortium led by W. L. Lyons. Accompanying them to the major leagues was their star player, infielder Pete Browning, who had already achieved some measure of local fame. The team got off to a good start, finishing in second place, their best finish for several seasons.

Managing partner Lyons resigned in mid-1888, with team secretary Mordecai Davidson taking over. The following season, the team sank to a 27–111 record and a last place finish. As a result, Davidson surrendered control of the team to the AA. In the 1896 season the Colonels lost five straight games in two days, including a tripleheader on September 7 and a doubleheader the next day, all against the Baltimore Orioles. With the prohibition of tripleheaders in the early 1920s, this record still stands. Even worse, the 1889 Colonels were the first team in major league history to lose 100 games in a single season.

In 1890 the team, which had been purchased by Barney Dreyfuss, bounced back with a vengeance. The Colonels won the 1890 pennant in the AA and became the first and only team to rise from the cellar to the pennant in one season. That year the AA was considered only the third-best behind the NL and the Players' League.

In 1892 the American Association dissolved, and the Colonels moved to the National League and played there until 1899. In 1900 Dreyfuss acquired controlling interest of the Pittsburgh Pirates and brought 14 Colonels players with him, including future Hall of Famers Honus Wagner and Fred Clarke, marking the end of the original Colonels organization and Louisville as a Major League Baseball host city.

In September 1882, Louisville pitchers threw two no-hitters in the span of nine days; Tony Mullane on September 11, followed by Guy Hecker on September 19. Other Louisville pitchers who threw no-hitters were Ben Sanders on August 22, 1892, and Deacon Phillippe, a rookie, on May 25, 1899. Pete Browning hit for the cycle twice for Louisville, on August 8, 1886 and June 7, 1889.
