Jarvis lasted just one at-bat with Brooklyn, was farmed back out, and according to his Baseball Reference page, he was drafted by the Pirates. He played minimally over two years there and his major league career was over at age 22.
He continued on in the minors, however, for quite awhile. It was tough finding a lot about that time in Jarvis' life, but we do know how he went from the Pirates system to San Francisco (PCL Independent) in 1949: it involves a trade for pitcher Bill Werle.
Werle's Baseball Reference page has the following for a deal sending him to the Pirates from San Francisco:
September 21, 1948: Traded by San Francisco (PCL) to the Pittsburgh Pirates for a player to be named later and cash. The Pittsburgh Pirates sent Steve Nagy (September 27, 1948) to San Francisco (PCL) to complete the trade.
We found this to be incomplete, though in this story from the St. Petersburg Times of Jan. 29 1949:
“The Pittsburgh Pirates yesterday released 22-year-old Catcher Leroy Jarvis outright to San Francisco of the Pacific Coast League as part payment for Pitcher Bill Werle”
“The deal for Werle was three players and an unannounced sum of cash. One of the players, Pitcher Steve Nagy, went previously.”
Many other articles of the day mention Jarvis as a part of this deal. I could not find the third player involved, however.
Jarvis bounced around the minors, AAA and AA until 1955. The only transaction I could find during that time was this from the Montreal Gazette of Feb. 25, 1954:
“Conditional sale of catcher Leroy Jarvis to Richmond of the International League was announced today by the Atlanta club of the Southern Association. No price was disclosed.”
Jarvis would only play 15 games for Richmond, and his career was done after a stop in Nashville.
Always interesting to find additions to known transactions.
