Righthander Bill Tremel started his pro baseball career in 1949 with the Clarksdale Planters of the Cotton States League as a free agent and the nineteen-year-old pitcher went 7-5 with a 4.28 ERA. Tremel spent six years in the minors (1949-1954) as a free agent until the Chicago Cubs purchased him from the Shreveport Sports of the AA Texas League on June 8, 1954.
A hard worker who would be in pro baseball for eleven seasons (1949-1959), Bill went 4-2 in 57 games out of the bullpen for the Cubs from 1954 to 1956. His first major league win came in 1954 against the Milwaukee Braves when he came on in relief to work seven scoreless innings. Tremel spent his entire major league run with the Cubs, appearing in 57 outings and going 4-2 with a 4.05 ERA during the three-year period.
Tremel, who did a lot of his minor league time in the Pacific Coast League and the Texas League during the 1950s had his best year early on in 1952 with Shreveport when he went 10-2 with a 3.97 ERA. Bill wound up his eleven-season minor league career with Shreveport in 1959 with a very creditable 72-60 record and a 3.99 ERA.
