- Before 1956 Season: Signed by the Chicago Cubs as an amateur free agent.
- July 7, 1961: Purchased by the Cleveland Indians from the Chicago Cubs.
- October 14, 1961: Purchased with Dave Tyriver by the Washington Senators from the Cleveland Indians.
I found that last deal in this article from the October 15, 1961 Reading Eagle:
“The Cleveland Indians announced today that pitchers Joe Schaffernoth and Dave Tyriver have been sent to the Washington Senators on a conditional basis.”
The bolding was done by me....as an "AHA" moment. The sale was conditional, and BOTH Schaffernoth and Tyriver were returned to the Cleveland club by the start of the next season. So we can add that to the deal.
On Tyriver's Baseball-Reference page, the return is mentioned, but not as a part of the same deal. Tyriver would make a couple of appearances for Cleveland in 1962.
Schaffernoth would play just two more years, both in the minors for Jacksonville. He was involved in one more transaction, though! From the April 7, 1964 Dayton Morning Journal:
“The (Toronto) Leafs management announced today the purchase of pitcher Joe Schaffernoth from the Cleveland Indian’s (sic) organization. Schaffernoth, then with the Jacksonville Suns, was the International League’s most valuable player in 1962.”
Schaffernoth never played for Toronto, which was an affiliate of both Milwaukee and Washington that season.
