Bryan Edmund "Moose" Haas spent twelve years in the Brewer organization, so when the Brewers traded him to Oakland on this day in 1986 it must have felt like the end of an era. The A's sent four players in exchange: Minor leaguers Mike Fulmer and Pete Kendrick, infielder Steve Kiefer and catcher Charlie O'Brien.

Haas had been the Brewers' second round pick in 1974 and spent his first ten major league seasons in Milwaukee, winning 91 games and posting a 4.03 ERA in 1542 innings. His best season was 1980, when he posted a 3.10 ERA over 252.1 innings, completing 14 games and pitching three shutouts. He's still among the top five Brewers of all time in several categories:

Haas pitched two seasons as a member of the A's before retiring.
