Jimmy Bonner

After returning to the United States, Bonner became a porter for the Pullman Company while continuing to play baseball semi-professionally. He joined the U.S. Army in 1943 and returned to Pullman after the war, where he worked until his death in 1963.

On September 8, 1936, Japanese-American businessman Harry H. Kono recruited Bonner to play for Dai Tokyo Baseball Club in the newly formed Japanese Baseball League. Dai Tokyo and the Nagoya Golden Dolphins had suffered from a lack of domestic talent, so they began to look towards the United States. On September 18, Bonner boarded the SS President Pierce bound for Japan, arriving on October 5. His salary was 400 yen a month, in contrast to the 140 yen average for a typical Tokyo Giants player. The Japanese press heralded his arrival with headlines like "Black Pitcher Rushes onto the Scene, Excellent Fielder, Holder of Amazing Strikeout Record." Bonner played several positions, including pitcher and first baseman. His record on defense in Japan was generally disappointing; he was far more successful on the plate, with a batting average of .458 in 24 at-bats. In mid-November, Bonner was dismissed after only a month on the team. Historians have come up with a variety of explanations for his poor performance as a pitcher in Japan, including a smaller strike zone due to the lower average height of Japanese men as well as the smaller and more slippery baseballs used in Japan compared to American balls.

Bonner began playing baseball in junior high, and by 1932 he was a utility player for the Shreveport Black Sports. At 5 feet 10 inches, he was ambidextrous, throwing right-handed and batting left-handed. Later that year, he moved to West Oakland, California, and married Lillian Victor from Waggaman, an unincorporated community near New Orleans. In 1934, he played for the San Francisco Colored Giants (not to be confused with the modern MLB franchise), and in 1935, joined the Oakland Black Sox. In 1936, he became a pitcher for the Berkeley Grays in the Berkeley International League, an ethnically diverse consortium of Bay Area teams. He gained the nickname "Satchel" for his impressive performances in the league, once throwing 22 strikeouts in a single game.
