In researching something else, I just realized that the recently deceased Moises Castro was briefly a member of the Denver Brewers organization. We signed him to a minor league contract prior to the 1966 season and his lone minor league All-Star game appearance came as a member of our AAA affiliate, the Chester Big Stick. He was then part of a multi-player trade we made with Brooklyn on July 25th of 1966 which also sent the Aces our veteran closer, Ron Poblano, and veteran outfielder Justin Schumann. In return the Brewers got a few players who briefly wore Brewers purple, one of whom, Billy Tanner, was a pretty significant member of the bullpen in 1967.
Somehow I missed this Brewer connection earlier and wanted to pass this information along now.
