1929 Green Sox
After playing several games with the Packers, Molenda went to California in early 1929 where he pitched in the winter league.[23] He reported to the Denver baseball team in the spring of 1929, but was able to secure his release when he learned of an industrial opening in Green Bay.[23] In June 1929, Molenda returned to Green Bay to establish his residence there and
signed a contract to play for Green Bay's professional baseball team, the Green Sox of the Bay Fox River Valley League.[23][24] Molenda had success for the Green Sox, striking out 14 batters in six innings of relief pitching in one game,[25] striking out 10 and 11 in other games,[26][27] and pitching a three-hit shutout.[28] Molenda pitched for the Green Sox again in the summer of 1931.[29]
