changing teams midseason but not ballparks

thanks for the work, Utter Chaos. I am surprised that the Mets and Yankees or Dodgers and Angels did not swap a player during 1974, 1975 and 62 to 65 respectively, when interleague trading was okay.

Since 1900, there's only a handful of Stadiums where this could happen:

A) 1911 Hilltop Park (Giants, Yankees)
B) 1913-1922 Polo Grounds (Giants, Yankees)
C) 1920-1953 Sportsman Park (Cardinals, Browns)
D) 1938-1954 Shibe Park (Phillies, Athletics)
E) 1962-1965 Dodger Stadium (Dodgers, Angels)
F) 1974-1975 Shea Stadium (Mets, Yankees)

George Uhle was the first player to play for the Giants and Yankees in the same year and that was in 1933 so A and B are out.
As mentioned Hornsby, Blake and White did it in St. Louis.
And nobody did it for Philadelphia, Los Angeles or New York.

So it looks like Hornsby, Blake, and White are the only ones to do it.

Because interleague trading was not allowed until the late 50s, an actual midseason trade is rare, if not impossible. Usually it's a release or a waiver situation.

Good question. I would imagine there was a mid season trade between the Yankees and Giants back when they both played at the Polo Grounds from 1913-1922.

which players in history were either traded from one team to another or released by one team and picked up by another, in mid-season, where the two teams share the same ballpark?

For Sportsman's Park, this oddity occurred first with Rogers Hornsby (1933), then Sheriff Blake (1937), and finally (fittingly in the last year of dual-occupancy), Hal White (1953).

But what about the other co-tenancy situations in major league baseball history?
