Just ran across this brief note in the June 5, 1920, Chicago Defender on the anticipated debut of a certain Army ballplayer with the Kansas City Monarchs:
The Monarchs are expecting a fellow soon, Rogan by name, and big leaguers who have seen him work pronounce him the best ever. He is with the 24th regiment and will report the middle of June.
A couple of interesting points: 1) this accords with Dave Wyatt’s statement, discussed here, that Wilkinson had signed Rogan “early last spring,” and more generally with the notion that Rogan’s arrival was planned well in advance, rather than occurring on the spur of the moment in St. Louis in late June or early July; and 2) he’s here said to be with the 24th rather than the 25th. Both units were stationed in Arizona in early 1920; it’s still not clear what the story is behind Rogan’s presence in St. Louis in January.
